About this unit converter
Recipes in cups, medical forms in pounds, weather in Fahrenheit, road signs in miles — the world refuses to agree on units, so conversion is a daily chore. This converter covers the eight categories people actually need: length, weight, temperature, area, volume, speed, data storage and time. Type a value once and the answer updates live, along with a full table showing that value in every unit of the category.
How to use it
- Pick a category — say, Weight.
- Enter your value and choose the unit it's in.
- Read the live result, or scan the table below it for all units at once. The ⇄ button flips the direction instantly.
Conversions people search for most
- 1 kg = 2.2046 lb — and a stone is 14 lb, which surprises everyone outside the UK.
- 1 inch = 2.54 cm exactly — the inch has been defined in metric terms since 1959.
- °F to °C: subtract 32, multiply by 5/9. Body temperature 98.6 °F = 37 °C.
- 1 mile = 1.609 km, and 1 knot (used by ships and planes) = 1.852 km/h.
- Data storage uses binary steps here (1 KB = 1024 bytes) — the convention operating systems use for file sizes.
For Nepali land units — ropani, aana, bigha, kattha — use the dedicated Nepali Land Area Converter, which handles the traditional survey system properly.
Frequently asked questions
Are the conversion factors exact?
Length, weight, area, volume and speed use the internationally defined exact factors (an inch is exactly 2.54 cm by definition). Results show up to 8 decimal places, more precision than any practical task needs.
Why does 1 KB show as 1024 bytes and not 1000?
The converter uses binary steps (1024) because that's how Windows, macOS and most software report file sizes. Drive manufacturers advertise in decimal (1000) — which is why a '1 TB' drive shows up as about 931 GB.
Does it convert Nepali land units like ropani?
For ropani, aana, bigha, kattha and dhur there's a dedicated Nepali Land Area Converter on this site that handles the traditional mixed-unit system properly, including breakdowns like '2 Ropani 6 Aana'.
