Compare Calculators

Mobile data and file sizes are measured in bytes, and keeping the units straight matters when you are choosing a package or downloading files. This Internet Data Usage Calculator converts between bytes, kilobytes, megabytes, gigabytes and terabytes so you always know the real size.

The calculation uses binary units (1,024 per step), which is how operating systems, apps and mobile data usage are actually measured — rather than the decimal units (1,000 per step) some storage vendors quote.

Pakistani mobile packages are sold in megabytes and gigabytes, while photos, videos and apps are measured in the same units. Converting between them helps you judge whether a 10 GB package covers your monthly usage.

The difference between decimal and binary units is real: a '1 TB' drive quoted in decimal shows less usable space in binary terms. This converter makes the relationship explicit.
