Enter a number in any field and click the “Calculate” button—or anywhere outside the field—to calculate the conversions.

Length

in = ft = m

Area

in2 = ft2 = m2

Volume

gal (US) = in3 = ft3 = dm3

Mass

lb = kg

Density

lb/ft3 = kg/m3

Force

lbf = kG = N

Torque

lbf·ft = kG·m = N·m

Pressure

in H2O = in Hg = mm Hg = lbf/in2 (psi) = atm = kG/cm2 (at) = mbar (hPa) = kPa

Energy

kcal = Btu = hp·h = kWh = kJ

Power

hp = metric hp = kW

Velocity

ft/min = mi/h = m/min = km/h = m/s

Flow Rate

ft3/min (cfm) = m3/h = m3/min = m3/s

Temperature

°F = °C

Fuel Consumption

mi/gal (US) = mi/gal (UK) = l/100 km
