About the Unit Converter

The Unit Converter converts values between dozens of units across eight categories: length (meters, feet, inches, miles), weight (kilograms, pounds, ounces, and tola for gold), temperature (Celsius, Fahrenheit, Kelvin), area (square feet, acres, hectares, and marla and kanal used in Pakistan and India), volume (liters, gallons, cups, spoons), speed, time and digital storage (both decimal megabytes and binary mebibytes).

Type in either box to convert in both directions, swap units with one click, and see the value in every unit of the category at once. Conversions use internationally defined exact factors, making the tool reliable for homework, cooking, travel, construction, property dealing and engineering.

Why your 1 TB drive shows about 931 GB

Drive makers use decimal units (1 TB = 1,000,000,000,000 bytes), while Windows counts in binary units of 1,073,741,824 bytes and still calls them GB. Nothing is missing. Compare MB and MiB in the digital storage category to see the difference.

Type in either box to convert in both directions, and use ⇄ to swap the units.
