Want to know the speed of your Internet connection you’ve contracted? When you see an ad on TV that offers, for example, a download speed of 300 Mbps, it should be noted that what they are selling us are 300 Megabits (Mb) per second and not 300 MegaBytes (MB).

The differences between the two units are very palpable when it comes to downloading files, music or movies online since these files are in KiloBytes, MegaBytes or GigaBytes. Below you have a calculator that we have designed so that you know the download or upload speed of your Internet connection from the data you have contracted.

## Does the data correspond to the Internet connection you have contracted?

Now that you have calculated the theoretical speed of your Internet connection, it is highly recommended that you do a speed test to check if the data obtained is close to what you have contracted.

Please note that the data obtained by the speed test will be less than the theoretical data obtained with our Internet speed calculator. How much lower? It depends on many factors although the most influence are the following:

• If you have fiber or ADSL connection. In the latter there is a lot of signal attenuation and the copper torque can reduce the speed of your connection if it is in bad condition.
• If you are connected to the router by cable or WiFi. If you’re using your wireless connection, get as close as you can to the access point so that distance isn’t another factor that slows down your connection.
• Closes apps that consume data in the background. If you are downloading any movies or music, using youtube, etc. Close all those tasks before starting the speed test or the results you’ll get will be fake. You should also make sure that no other devices are connected to your connection and are consuming bandwidth.
• Distance from your home to the service provider. This is something that influences the case of ADSL more because of what we discussed in the first point. If you have fiber, the attenuation is much less and the signal arrives practically full to your home, so you will have the speed that you have contracted almost safely.

If Internet still goes very slow and the speed test differs greatly from the results obtained with our calculator, then call your operator and ask them for an explanation because they are not meeting the conditions agreed in the contract.

## How to calculate the speed of your Internet connection?

Let’s take an example. Imagine that your connection is 20 Mbps download and 600 Kbps upload. You enter that data in the calculator and you will see that you can download files at a maximum speed of 2.38 MB/s and get an upload speed of 73.24 KB/s.

Of course, these values are theoretical so you’re likely to actually get much lower results. This is due to multiple technical factors such as wiring status, distance from your home to the service provider (if using fiber, to FTTH point), etc.

Still, it can be worth it as an orientation in case you’re thinking about switching carriers and want to get an idea of how fast your Internet connection might reach.  Now you can use  Download Time Calculator – Calculate Download Time  and estimate everything.

NOTE: Since an hour includes 60 minutes (and not a hundred minutes), adding time takes a little time.
Hours and minutes are two different units that measure
time. However, the minutes are not a
decimal number of hours, that is, (0.5 of an hour) is not 50 minutes, it is 30 minutes… making time calculation a test of ingenuity.
Adding time with a conventional calculator requires you to first convert your minutes into a decimal number, dividing the minutes by 60.
