The download time is determined by the connection speed between the two devices and the size of the transferred file. The connection speed is determined by the hardware capabilities of the two devices and also the ISP Internet Service Provider that they use. A faster connection speed will result a faster download and shorter download time. Of course, a smaller file will require shorted download time too.
Download speed is the amount of data that is transferred per second between two Internet-connected devices. It may be expressed in various units which are multiples of a BIT - the smallest unit in computers. Those are bits, Kilobits, Megabits, Gigabits and so on. To convert Kilobits to Megabits you have to divide them by To convert the Megabits to Gigabits you have to divide them to again and so on. The download speed is determined by your service provider and the hardware limits of the connection.
For example the highest download speed of a Base-T connection is Megabits. Of course that speed is the maximum that can be reached on such hardware and may be slower based on the Internet plan that you have signed for. You can check your download and upload speeds at SpeedTest. The download and upload speed are usually different. In most cases the upload speed is much slower than the download speed. If the two are equal we call such connection symmetric.
If the connection is not "shaped" limited by an ISP it is symmetric by default. Now that we know how to determine the transfer speed for our uploads and downloads, we can now calculate a file's download time or duration. Calculating download time is as simple as dividing the size of the file you wish to transfer by the transfer speed of the network that the transfer will go through.
However, we have to be careful with the units we use, since this could be quite confusing. Let us consider the example above for our sample computation. To calculate how long to download the MB video over a 5 Mbps internet download speed, we can use the equation below:. But first, let us convert the units of the file size in terms of megabits, which is equivalent to 1 million bits. To do so, we'll be using the conversion table above under the SI system.
With that said, we now have this computation:. As shown above, the MB video file will finish downloading in less than 11 minutes over a stable 5 Mbps connection. However, if somebody else in the house uses the internet while you're downloading this video file, it could take much longer to complete the download because of congestion in the data transfer. Aside from calculating the download time of a file from the internet, you can also use this calculator to determine the transfer duration from, let's say, a computer to an external storage device like a USB flash drive.
However, you must first know the transfer rate of your connection to calculate the transfer duration. You can also use this download time calculator to determine your download speed. However, for this, you have to time how long to download a particular file. Then, by entering the file size and the download time in our calculator, you'll be able to calculate your internet's download speed. If you want to determine the actual time your download will take to complete, you can input the estimated download time into our time duration calculator.
Our time duration calculator will help you determine the actual completion time of the download. Embed Share via. Table of contents: Understanding computer file sizes Why we download computer files Upload and download speeds How to determine download time Download completion time FAQ.
Understanding computer file sizes Computer file sizes vary depending on the amount of data or information a computer file stores. Why we download computer files Files cannot always be in just one computer or machine.
Upload and download speeds Uploading and downloading data can take a while, depending on the file's size and transfer rate. How to determine download time Now that we know how to determine the transfer speed for our uploads and downloads, we can now calculate a file's download time or duration.
Download completion time If you want to determine the actual time your download will take to complete, you can input the estimated download time into our time duration calculator. FAQ What are the factors affecting download time? The download time for a file depends on two factors, which are: File size; and Speed of your internet connection. How to estimate download time for data?
To estimate download time: Find out the internet data speed. Note down the file size. Make sure the units for the bits is the same. Divide file size by data speed to obtain download time. Tips and Warnings. Related Articles. Article Summary. Part 1. Check your download speed. This will give you an estimate of your computer's current download speed. If you see that your download speed is significantly faster than files are actually downloading, the problem most likely isn't with your Internet.
If your download speed is much slower than your Internet package and router allow for, you need to minimize the number of devices connected to the Internet. Disconnect any non-essential devices from the Internet. The more devices you have on your network, the slower your Internet will be. If you can disable consoles, phones, televisions, tablets, and alternate computers, your own computer's downloads will be faster. Disable any apps you aren't using. When you're downloading a big or a small file, it helps to turn off apps that are taking up your bandwidth.
For example, you'd close BitTorrent if it was running in the background while you attempted to download a Windows update. Netflix, Hulu, and even YouTube can be a serious drain on your download speed. Even if it's only by a marginal amount, disabling these services will boost your download speeds. You should also close any non-essential browser windows or tabs. Try connecting your computer to your router via Ethernet.
If your computer isn't using an Ethernet connection, connect it to your router with an Ethernet cable and see if your downloads increase in speed. If your downloads do increase in speed, your wireless connection to the router is poor. Try staying closer to the router or purchasing a stronger router. If the download speed doesn't increase, the problem is either with the router or your computer. You can reset your router's cache by unplugging both the router and the modem, waiting for a minute or so, and then plugging everything back in.
Avoid seeding or uploading while attempting to download. As noble as it may be to give back to your favorite torrenting community by uploading, doing so while downloading will all but kill your download speeds. Wait to seed until all of your downloads have completed and you're no longer using the Internet e.
Force your protocol encryption if you're using a torrenting service. This action disguises what you're downloading so that your ISP doesn't selectively throttle it. ISPs will throttle if they know a BitTorrent client is doing a lot of downloading. Click Preferences. Click BitTorrent. Click the "Outgoing" drop-down box.
Select Forced. Click Apply , then click OK. Buy a new router. If your router is more than a couple of years old, it will invariably begin to slow down, and it won't handle downloads as well as a newer one.
When purchasing a new router, make sure you look at models that support the same download speed as your Internet package or, ideally, higher download speeds. Upgrade your Internet connection speed. Some Internet connections simply aren't able to handle hefty downloads, such as console or computer game installations. Many ISPs have a "Gamer" package that prioritizes download speed, though you'll likely have to pay significantly more for this package than you would for a standard Internet package.
Contact your Internet Service Provider. If you've tried everything else and you can't get your download speeds to increase, you'll need to call your ISP and tell them about the problems you're experiencing. You may even need to switch your ISP if you live in a remote-enough area. Part 2.
Click Change adapter options. This option is beneath the "Change your network settings" heading on the Status tab. Click your current connection's name. It will be on the Connections page. This will select it. Click Change settings of this connection.
This button is in the top row of options in the window. Clicking it will open the connection's settings. It's in the window that's in the middle of Wi-Fi Properties. You may first need to click the Networking tab at the top of Wi-Fi Properties. Click Properties. It's near the bottom of the window. Check the "Use the following DNS server addresses" circle. It's near the bottom of the Properties window. Enter a preferred DNS address. Do so in the "Preferred DNS server" field.
Google - Enter 8. Enter an alternate DNS address. Click OK. This saves your DNS settings.
