Pressure
1 bar = 0.1 megaPascal (MPa) = 14.5 lbf/square inch (PSI)
5,000 psi = 345 bars = 34.5 MPa
10,000 psi = 689 bar = 68.9 MPa
Volume
1 standard cubic foot = 28.3 liters
[standard conditions are atmospheric pressure and 60°F (16°C)]
Mass
1 kilogram = 2.2 pounds
Energy
1 British thermal unit (Btu) = 1,055.05585262 joules (J)
1 calorie (cal) = 4.1868 joules (J)
1 kilowatthour (kWh) = 3.6 megajoules(MJ)
Temperature
°C = (°F-32) x 5/9
