How to use

How it works
Conversions use exact international definitions where they exist — for example 1 inch = 2.54 cm and 1 pound = 0.45359237 kg exactly. Digital storage shows both decimal units (1 GB = 1,000,000,000 bytes, used by drive makers) and binary units (1 GiB = 1,073,741,824 bytes, often used by operating systems). The page address remembers your choice, so you can bookmark a conversion.
Limitations
- Months and years use Gregorian averages (30.436875 and 365.2425 days).
- US and UK gallons, pints and tons differ; both are listed separately.
- Regional units such as bigha vary from place to place and are not included.
