What is the Unit Converter?

A unit converter changes a measurement from one unit to another — feet to meters, pounds to kilograms, US or UK gallons to liters, °F to °C. AnyShift covers 13 categories: length, weight, volume, area, temperature, speed, time, data, energy, pressure, power, fuel economy and angle, using exact international definitions such as 1 inch = 2.54 cm, 1 lb = 0.45359237 kg and 1 US gallon = 3.785411784 L.

Type a value to see the answer plus a table converting it to every other unit in that category. US and UK (imperial) volumes and mpg are listed separately, because a UK gallon (4.546 L) is about 20% larger than a US gallon. Conversions run in your browser.

  1. Choose a category: Length, Weight, Volume, Area, Temperature, Speed, Time, Data, Energy, Pressure, Power, Fuel economy or Angle.
  2. Enter the Value and pick the From and To units.
  3. Read the result instantly; click ⇄ to swap the units.

Frequently asked questions

How do I convert Fahrenheit to Celsius?
Subtract 32 and multiply by 5/9: °C = (°F − 32) × 5/9. So 98.6 °F = 37 °C and a 350 °F oven is about 177 °C. To go the other way, °F = °C × 9/5 + 32.
Is a UK gallon the same as a US gallon?
No. A UK (imperial) gallon is 4.546 liters and a US gallon is 3.785 liters, so 1 UK gallon ≈ 1.2 US gallons. UK pints (568 ml) and fluid ounces (28.4 ml) also differ from US pints (473 ml) and fluid ounces (29.6 ml).
How do I convert mpg to L/100 km?
Divide 235.21 by US mpg, or 282.48 by UK mpg. For example, 30 mpg (US) = 7.84 L/100 km and 40 mpg (UK) = 7.06 L/100 km.
What is the difference between MB and MiB?
A megabyte (MB) is 1,000,000 bytes; a mebibyte (MiB) is 1,048,576 bytes (1024²). Drive makers use decimal units, while Windows reports binary units labelled GB, which is why a 1 TB drive shows about 931 GB.
How many pounds are in a stone?
14 pounds, or about 6.35 kg. To convert 11 st 7 lb, enter 11.5 stone: that is 161 lb or about 73 kg.
Are cup measurements the same in every country?
No. This converter uses the US customary cup (236.6 ml). Australia, New Zealand and most Canadian recipes use a 250 ml metric cup, and an Australian tablespoon is 20 ml rather than about 15 ml.
