How to convert data sizes
Type a size and choose the units, for example GB to MB.
Why is my 128 GB phone showing less?
Makers count 1 GB as 1,000,000,000 bytes. Computers often count in binary, where 1 GiB is 1,073,741,824 bytes, and Windows labels that GB too. So 128 GB shows as about 119 GiB, before the system takes its share.
Internet speed
Internet packages are sold in megabits (Mbps). Divide by 8 for megabytes: a 40 Mbps connection downloads up to 5 MB a second.
Is anything I type saved?
No. The numbers are worked out in your browser and are not sent anywhere.
