Temperature Conversions

°C to °F or Celsius to Fahrenheit Calculator °F = °C x 5 / 9 + 32
°F to °C or Fahrenheit to Celsius Calculator °C = (°F - 32 ) x 5 / 9

Pressure Conversions

kPa to psi, 0.145038 lbs/in² = 1kPa / 6.89479 (kPa / psi) or Divide kPa by 6.89479
psi to kPa, 6.89476 kPa = 1 psi (multiply psi by 6.89476)

Volume Conversions

m³/ kg to in³/lbs, 27679.9 in³/lbs = 1 m³/ kg, ( multiply m³/ kg by 27679.9 to get in³/lbs )
in³/lbs to m³/ kg, 3.6127 x 10^-5 m³/ kg = 1 in³/lbs ( divide in³/lbs by 3.6127 x 10^-5 )

Energy Conversions

BTU/lbs to kJ/kg, 1 kJ/k = 0.429923 BTU/lbs ( multiple BTU/lbs by 0.429923 )
kJ / kg to Btu / lbs, 1 BTU/lbs = 2.326 kJ/kg ( divide kJ/kg by 2.326 )
