How to calculate download time theoretically?

It's easy too once you understand the rules and basics of the calculations.

This is the simplest formula you can use to calculate download time.

calculate download time = file size / internet download speed

But this doesn't define anything clearly, right?

So let's break it down in short.

File sizes are generally in KB, MB, or GB. Similarly, internet speed is also denoted in Kbps, Mbps Gbps.

Now you need to keep in mind that GB is not equal to Gb. Capital B is to denote byte but small b is to denote bit.

8 bits= 1 byte or 1 bit=1/8 byte.

And therefore when there are capital letters like KB, MBps, and so on then it's in the byte format.

That means 1 KB is Kilobyte and 1 Kb is Kilobit.

Look at this table to understand file sizes and internet speed better.

You can clearly see all the data that you generally process in day-to-day life.

ISP uses the small letter while showing the internet speed like Kbps, Mbps, Gbps, etc.

But the internet and most general applications use capital letters while showing the download speed.

That's why it's always a misconception between the internet speed and the download speed.

Your 10Mbps internet pack is equal to 1.25 MBps download speed.

Hence in order to calculate download time accurately, I designed this download time calculator so that anyone can easily calculate estimated download time.

It's very easy and simple too.

You can choose your exact download speed from the available options and file sizes too and then this download time calculator will give you the output in hh:mm: ss format.

That means it will calculate download time and will give you how many hours, minutes, and seconds are left in order to download that file from the internet.
