Caps count bytes, not bits

A data allowance is quoted in gigabytes while your line is sold in megabits per second. Dividing by eight is what connects the two: a 100 Mbps line running flat out moves about 10.6 MB every second, which is more than 3 TB in a month.

What is the Data Transfer Calculator?

Data Transfer Calculator checks the total amount of data transferred based on your connection speed and the duration of the transfer. It's useful for estimating monthly data usage, planning backups, or monitoring bandwidth consumption over time.

Key Features Data Transfer Calculator
