Calculators


All of our electric heater calculators in one place. 

Power Flowrate Temp Calculator

Calculate the electrical power, flow rate or temperature requirement as follows:

  • 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

Temperature Conversion Calculator

°F = ( ( ( °C * 9) / 5 ) + 32 )
°C = ( ( ( °F - 32) * 5 ) / 9 )

Fill in one value to calculate the other

Three Phase Unit Calculator

Line Current = Wattage / (Voltage * √3)

Fill in two values to determine the third

Single Phase Unit Calculator

Line Current = Wattage / Voltage

Fill in two values to determine the third

Ohms Law Calculator

Fill in two values to determine the other two

Heat Transfer Through Convection Calculator
  • 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 to SCFM Calculator
  • 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 to Volumetric Flow Calculator

Mass flow rate to Volumetric flow rate for air

Fill in one value to calculate the other two
