About BTU per Hour (IT)
BTU per hour expresses thermal power using the IT British thermal unit (≈ 1,055.056 J per BTU), divided by one hour. Common in HVAC equipment ratings.
About Kilowatt
One kilowatt is 1,000 W. Motor, heater, and grid-scale loads are often rated in kW.
How to convert btu per hour (it) to kilowatts
1 btu per hour (it) is equal to 0.00029307107017 kilowatt when both are expressed in watt-equivalents:
1 btu_hr = (0.2930710701722222 W ÷ 1,000 W) kw = 0.00029307107017 kw
Each btu per hour (it) is defined as 0.2930710701722222 W and each kilowatt as 1,000 W in this tool, so one btu_hr equals 0.2930710701722222 ÷ 1,000 kw = 0.00029307107017 kw.
Let d(btu_hr) be the numeric value in BTU per Hour (IT) (btu_hr), and d(kw) the value in Kilowatt (kw). Then:
d(kw) = d(btu_hr) × (0.2930710701722222 / 1,000)
Equivalently, divide by how many btu_hr fit into one kw (watts per kw divided by watts per btu_hr):
d(kw) = d(btu_hr) ÷ 3412.14163312794199
Or: kilowatt = btu per hour (it) ÷ 3412.14163312794199
Examples
Example #1: Convert 1 btu_hr to kilowatt
1 btu_hr = 1 btu_hr × (0.2930710701722222/1,000) kw = 0.0002930711 kw
1 btu_hr = 1 btu_hr ÷ 3412.14163312794199 = 0.0002930711 kw
Intermediate watts: 0.2930710702 W
Example #2: Convert 10 btu_hr to kilowatt
10 btu_hr = 10 btu_hr × (0.2930710701722222/1,000) kw = 0.0029307107 kw
10 btu_hr = 10 btu_hr ÷ 3412.14163312794199 = 0.0029307107 kw
Intermediate watts: 2.9307107017 W
Summary
To convert BTU per Hour (IT) to Kilowatt, multiply the value in btu_hr by the ratio of watts per btu_hr divided by watts per kw. Equivalently: value_kw = value_btu_hr × (0.2930710701722222 / 1000). Numerically, 1 btu_hr equals 0.0002930710701722222 kw.
Relationship context
You are converting between thermal engineering rates (BTU/h, kcal/h) (BTU per Hour (IT)) and SI / decimal power (watts and prefixes) (Kilowatts). All linear values are mapped through watts first. The numeric factor is 2.930711e-4.
