How the Unit Converter works

Choose what you want to convert — length, weight, temperature, area, volume, speed, time, data storage, pressure or energy — then enter a value and pick the units. The result updates as you type, and the table below shows the same value in every unit of that kind.

Most units convert by multiplying by a fixed factor through a base unit (for example, everything in length goes through meters). The factors are exact international definitions where one exists: one inch is exactly 2.54 cm and one pound is exactly 0.45359237 kg.

Formulas

Linear units

result = value × (ffrom ÷ fto)

Where:

ffrom
Size of the starting unit in the base unit (1 ft = 0.3048 m)
fto
Size of the target unit in the base unit

Temperature

°F = °C × 9 ÷ 5 + 32  ·  K = °C + 273.15

Temperature scales have different zero points, so they need an offset as well as a factor. Values below absolute zero (−273.15 °C) are rejected because they can't exist.

Examples

5 feet 10 inches in centimeters

70 in × 2.54 = 177.8 cm

70 kg in pounds

70 ÷ 0.45359237 = 154.32 lb

Body temperature in Fahrenheit

37 × 9 ÷ 5 + 32 = 98.6 °F

Why a “1 TB” drive shows 931 GiB

1 TB = 1012 bytes ÷ 10243 = 931.32 GiB. Drive makers use decimal units; many operating systems show binary ones.

Frequently asked questions

What's the difference between MB and MiB?

A megabyte (MB) is 1,000,000 bytes (decimal, used by storage makers). A mebibyte (MiB) is 1,048,576 bytes (220, binary, often used by operating systems). The converter supports both.

Are US and UK gallons the same?

No. A US gallon is 3.785 liters; a UK (imperial) gallon is 4.546 liters. US cups, pints and fluid ounces are used for the other volume units.

How precise are the results?

Calculations use exact factors and are shown to up to 10 decimal places, with very large or small values in scientific notation. Month and year use average lengths (30.44 and 365.2425 days).
