📚 Key HVAC Conversion Factors

RelationshipConversion
1 ton refrigeration= 12,000 BTU/hr = 3.517 kW = 3,517 W
1 MBH= 1,000 BTU/hr = 0.2931 kW = 0.08333 tons
1 HP (mechanical)= 2,545 BTU/hr = 0.7457 kW = 745.7 W
1 therm= 100,000 BTU = 29.307 kWh = 8.33 ton-hr
1 in. w.c.= 249.1 Pa = 0.0361 psi = 0.0833 ft H₂O
1 GPM water= 500 BTU/hr per °F ΔT (sensible factor)
1 CFM air (sensible)= 1.08 BTU/hr per °F ΔT (sea level)
1 CFM air (latent)= 0.68 BTU/hr per gr/lb Δω (sea level)
