Storage Capacity Calculator

It takes Capacity and File type and derives Files that fit from them. The calculation is live as you type, so the result updates on every change.

2 values: Capacity (GB) and File type. Nothing else is required — no account, no file upload.

With Capacity = 64 GB and File type = Photo (4 MB), the calculator returns Files that fit = 16,384. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

It moves a lot. Using Capacity = 128 GB and File type = Song (5 MB) instead, Files that fit goes from 16,384 to 26,214 — which is why it is worth testing a few scenarios rather than trusting a single figure.

You can pick between « Photo (4 MB) », « Song (5 MB) », « HD video minute (50 MB) » and « Document (0.1 MB) ». Each one changes what the calculator works out, so switch and compare — the default is « Photo (4 MB) ».

Enter Capacity GB.

Scaled down to Capacity = 32 GB and File type = Photo (4 MB), Files that fit comes out at 8,192. The relationship is worth checking at both ends before you rely on a single result.

Finding out how big a thing will be before you make it: how many gigabytes an hour of footage takes, how long a file needs on the connection you have, how large a photo prints before it goes soft, what bitrate fits the budget you were given.

Taking the advertised connection speed as the transfer speed. A 100 Mb/s line is megabits, the file is in megabytes, and the eight-fold difference between them is where most download estimates go wrong — before overhead and contention take their own share.

This one returns Files that fit; the Audio file size calculator returns File size (MB). That is the whole difference — open the one whose figure you need.
