Domestic Household energy use
Cooling units and conversions often used in Energy Modeling of Buildings:
Cooling tons vs. Btu
Btu per hour = sometimes written as: Btuh or Btu/h or Btu/hr
Cooling hvac conversion:
1= (1 ton*hr cooling)
(12,000 Btu)
1= (1 ton cooling)
(12,000 Btu/hr)
Cooling Tower conversion:
1= (1 cooling tower ton)
(15,000 Btu/hr)
Chilled water gpm vs. ton
No Glycol, Temperature units in Fahrenheit
Btu/h = (1 (constant units: Btu/lbm * F)) * [constant: 8.33(lbm/gal)] * [variable: gpm] * [variable: Delta T]
Cooling horse power (not motor horse power)
"Amount of cooling output in units of horse power"
Note: Cooling horsepower is sometimes referred to as the motor nameplate horse power of the compressor motor in some industries.
1 = 1 hp
.746 kW
Chiller equation:
Tons = (GPM DELTA T) Temperature in Fahrenheit Approximately From chillers.com

Mbtu, MMBtu, Btu
1= mmBtu
1,000,000 Btu
mmBtu = "million" btu or "Thousand thousand" btu
This uses the Roman Numeral value "m", not to be confused with roman numeral "M"
BEWARE:
MBt does not = 1,000 btu, Only in Equest Result sim file output
it may also be labeled as:
mBtu=1,000,000 btu, Only in Equest Results sim file output
-Note: 1= apples
oranges
These conversions use the unitary multiplication method.
