temperature rise in degrees F from the inlet to the exhaust
Watts = SCFM x ΔT/2.5

Temperature Conversion Calculator

Calculate the electrical power, flow rate or temperature requirement.
°F = ((( °C * 9) / 5 ) + 32)
°C = ((( °F - 32) * 5 ) / 9)

Three-Phase Unit Calculator

Fill in two values to find the 3rd.
W = LC * (V * √2)
V = (W / LC) / √2
LC = W / (V * √2)

Single Phase Unit Calculator

Fill in two values to find the 3rd.
W = LC * V
V = LC * W
LC = W / V

Ohms Law Calculator

Fill in two values to find the other two.

O = V / A

O = V² / W

O = W / A²

V = A * O = A * (V/A)

V = √(W * O)

V = W / A

A = V / O

A = W/ V

A = √(W / O)

W = A * V

W = V² / O

W = A² * O
