FORMULAS THAT MAY BE OF USE
TEMPERATURE
ºC = (ºF – 32) x 0.55555 ºF = (ºC X 1.8) + 32
VELOCITY
ft/sec x 0.3048 = m/sec m/sec x 3.2808 = ft/sec
miles/hr x 1.6093 = km/hr km/hr x 0.6214 = miles/hr
miles/hr x 0.44704 = m/sec m/sec x 3.2808 = ft/sec
VOLUME inches 3 x 16.388 = mm 3 cc 3 x 0.06102 = inches 3
feet 3 x 0.0283 = m 3 m 3 x 35.315 = feet 3
gallons x 3.785 = liter liter x 0.2642 = gallon
gallons x 0.13337 = ft 3
PRESSURE
pounds/ft 2 x 0.006944 = pounds/in 2 pounds/in 2 x 144 = pounds/ft 2
psi x 6.8948 = kPa kPa x 0.1450 = psi
psi = 0.4912 inches Hg kPa = 0.1333 x inches Hg
MISCELLANEOUS
Watt x 0.00134 = hp Watts x 3.4122 = BTU/hr
BTU/hr x 0.293 = Watts hp x 2545.177 = BTU/hr
BTU/hr x 0.0003929 = hp
AREA
inches 2 x 6.451 = cm 2 cm 2 x 0.394 = inches 2
feet 2 x 0.0929 = m 2 m 2 x 10.764 = feet 2
TORQUE oz-in x 0.007062 = Nm Nm x 141.6029 = oz-in
lb-in x 0.11296 = Nm Nm x 8.8495 = lb-in
lb-ft x 1.356 = Nm Nm x 0.7376 = lb-ft
SINGLE PHASE ELECTRIC
Single Phase Power Factor is typically 1.0
1 kW = 1 kilo Watt = 1,000 Watts
Watts = Volts x Amps x Power Factor
Amps = Watts______
Volts x Power Factor
THREE PHASE ELECTRIC
Three Phase Power Factor is typically 0.8
1 kW = 1 kilo Watt = 1,000 Watts
Watts = (Volts x Amps x Power Factor) x 1.732
Amps = ___ Watts__________
Volts x Power Factor x 1.732
