USEFUL HVAC CONVERSION MEASURES:

  • 1 HP= 0.746 KW = 746 Watts = 2,545 BTU/h = 1.0 kVA
  • 1 KW= 1,000 Watts = 3,413 BTU/h = 1.341 HP
  • 1 Watt = 3.413 BTU/h
  • 1 Ton Ac = 12,000 BTU/h Cooling = 15,000 BTU/h Heat Rejection
  • 1 BTU/h = 1 BTU per hour
  • 1 BHP = 34,500 BTU/h (33,472 BTU/h) = 34.5 Lb. Steam per hour = 34.5 Lb. H2O/Hr. = 0.069 GPM = 4.14
  • GPH = 140 EDR (Sq. Ft. of Equivalent Radiation)
  • 1 Therm = 100,000 BTU/h
  • 1 MBH = 1,000 BTU/h
  • 1 Lb. Stm./Hr. = 0.002 GPM
  • 1 GPM = 500 Lbs. Steam per hour
  • EDR = Equivalent Direct Radiation
  • 1 EDR = 0.000496 GPM = 0.25 Lbs. Steam Condensate per hour
  • 1000 EDR = 0.496 GPM
  • 1 EDR Hot Water = 150 BTU/h
  • 1 EDR Steam = 240 BTU/h
  • 1 EDR = 240 BTU/h (Up to 1,000 Ft. Above Sea Level)
  • 1 EDR = 230 BTU/h (1,000 Ft–3,000 Ft. Above Sea Level)
  • 1 EDR = 223 BTU/h (3,000 Ft.–5,000 Ft. Above Sea Level)
  • 1 EDR = 216 BTU/h (5,000 Ft.–7,000 Ft. Above Sea Level)
  • 1 EDR = 209 BTU/h (7,000 Ft.–10,000 Ft. Above Sea Level)
