How do you convert between units of measurement?
To convert units, pick a category (length, weight, temperature, area, or speed), choose the from and to units, and type a value. Conversions use exact factors: 1 mile is 1,609.344 metres, 1 pound is 0.453592 kilograms, 1 acre is 4,046.86 square metres, and 1 knot is 1.852 km/h. Temperature converts through Celsius.
How do you convert Fahrenheit to Celsius?
Subtract 32 from the Fahrenheit temperature, then multiply by 5/9. For example, 98.6°F minus 32 is 66.6, and 66.6 times 5/9 is 37°C. Going the other way, multiply Celsius by 9/5 and add 32. Kelvin is simply Celsius plus 273.15, so 0°C equals 273.15 K.
