Unit Converter (Length, Weight, Temperature and More)

How to use the Unit Converter (Length, Weight, Temperature and More)

1. Choose the type of unit, for example Length or Temperature.
2. Type a value, then pick the unit it is in (From) and the unit you want (To).
3. The result and a table of every unit of that type appear as you type. There is no Copy button, so select the figures you need.

Example

Worked example (run through this tool)

• Length: 1 mile: 1.609344 km, 1,760 yards, 5,280 feet, 63,360 inches
• Weight: 1 kilogram: 2.20462262 pounds, 35.27396195 ounces, 0.15747304 stone
• Temperature: 20 °C: 68 °F and 293.15 K; -40 °C is -40 °F
• Volume: 1 UK pint: 568.26125 ml, 20 UK fluid ounces, 0.15011874 US gallons
• Speed: 1 mph: 1.609344 km/h, 0.44704 m/s, 0.86897624 knots
• Area: 1 square foot: 0.09290304 m², 0.11111111 square yards
• Data: 1 GB and 1 GiB: 1 GB is 1,000 MB; 1 GiB is 1,073.741824 MB, or 1,024 MiB
• Time: 1 hour: 60 minutes, 3,600 seconds, 0.04166667 days

Limitations

• Results show up to eight decimal places, so very small values can round to zero. Temperature shows four.
• Volume has UK and US units, which differ: a UK pint is 568.26 ml and a US pint is about 473 ml. Cups, tablespoons and teaspoons here are US measures.
• Temperature values below absolute zero are not rejected: -300 °C gives -26.85 K, which is physically impossible.
• In data storage, KB, MB, GB and TB use 1,000 while KiB, MiB and GiB use 1,024, which is why a drive shows less capacity than its label.
• Months and years in the time converter are averages (about 30.44 days and 365.24 days), not calendar months. Use the Date Difference Calculator for real dates.
• A stone is 14 pounds, but the weight converter shows decimals of a stone. Troy ounces and nautical miles are not included.
