Common Units Converter, meteric <--> imperial

Temperature conversion

Length/Distance conversion

Area conversion

Volume conversion

Weight conversion

Pressure conversion

Speed conversion

Speed is expressed in length per time. However there are some special units:

Speed of light in vacuum= 1079252848.8 kilometer/hour = 299792458 meter/second
Speed of sound in air [mach]= 1225.044 kilometer/hour = 340.29 meter/second
1 knot = 1.852 kilometer/hour = 0.514 meter/second
1 mile/hour (mph) = 1.609344 kilometer/hour (km/h), use above length converter for mile and kilometer

Special names

Some old units in the metric system use old names that do not have the power prefixes. Those are:

1 millibar = 1hpa (hectopascal)
Liter: 1l = 1dm³ (cubic decimeter)
Tonn: 1t = 1000kg
1 are = 100 square meter = 100m², 1 hectare=10,000m²=0.01km²

Power prefixes used within the units of the metric system

No converter is needed to convert among the units of the metric system. You just multiply or divide by a factor which is given by the power prefix.
Example: 1km (kilometer) = 10³ m (meter)= 1000m (meter)
