Calculators
All of our electric heater calculators in one place.
Calculate the electrical power, flow rate or temperature requirement. Check our visual and interactive explanation.
- SCFM = airflow in standard cubic feet per minute
- ΔT = temperature rise in degrees F from the inlet to the exhaust
- Watts = SCFM x ΔT/3
Fill in two values to determine the third
°F = ( ( ( °C * 9) / 5 ) + 32 )
°C = ( ( ( °F - 32) * 5 ) / 9 )
Fill in one value to calculate the other
Line Current = Wattage / (Voltage * √3)
Fill in two values to determine the third
Line Current = Wattage / Voltage
Fill in two values to determine the third
Fill in two values to determine the other two
- ρ = density (lb/ft3)
- V = volume flow rate (ft3/hour)
- Cp = specific heat (Btu/lb°F)
- Ta-Tb = temperature differential (°F)
- Q = ρ x V x Cp x (Ta-Tb)
Fill in four values to determine the fifth
- ACFM = airflow in actual cubic feet per minute
- P = gage pressure (psi)
- T = gas temperature °R = 460 + °F
- SCFM = airflow in standard cubic feet per minute
Fill in 3 values to determine the SCFM
Mass flow rate to Volumetric flow rate for air
Fill in one value to calculate the other two
