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 )
