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 Gigawatt
One gigawatt is one billion watts. Utility generation capacity and grid planning commonly use GW.
How to convert btu per hour (it) to gigawatts
1 btu per hour (it) is equal to 2.93071070e-10 gigawatt when both are expressed in watt-equivalents:
1 btu_hr = (0.2930710701722222 W ÷ 1,000,000,000 W) gw = 2.93071070e-10 gw
Each btu per hour (it) is defined as 0.2930710701722222 W and each gigawatt as 1,000,000,000 W in this tool, so one btu_hr equals 0.2930710701722222 ÷ 1,000,000,000 gw = 2.93071070e-10 gw.
Let d(btu_hr) be the numeric value in BTU per Hour (IT) (btu_hr), and d(gw) the value in Gigawatt (gw). Then:
d(gw) = d(btu_hr) × (0.2930710701722222 / 1,000,000,000)
Equivalently, divide by how many btu_hr fit into one gw (watts per gw divided by watts per btu_hr):
d(gw) = d(btu_hr) ÷ 3.41214163e+9
Or: gigawatt = btu per hour (it) ÷ 3.41214163e+9
Examples
Example #1: Convert 1 btu_hr to gigawatt
1 btu_hr = 1 btu_hr × (0.2930710701722222/1,000,000,000) gw = 0.0000000003 gw
1 btu_hr = 1 btu_hr ÷ 3.41214163e+9 = 0.0000000003 gw
Intermediate watts: 0.2930710702 W
Example #2: Convert 10 btu_hr to gigawatt
10 btu_hr = 10 btu_hr × (0.2930710701722222/1,000,000,000) gw = 0.0000000029 gw
10 btu_hr = 10 btu_hr ÷ 3.41214163e+9 = 0.0000000029 gw
Intermediate watts: 2.9307107017 W
Summary
To convert BTU per Hour (IT) to Gigawatt, multiply the value in btu_hr by the ratio of watts per btu_hr divided by watts per gw. Equivalently: value_gw = value_btu_hr × (0.2930710701722222 / 1000000000). Numerically, 1 btu_hr equals 2.930710701722222e-10 gw.
Relationship context
You are converting between thermal engineering rates (BTU/h, kcal/h) (BTU per Hour (IT)) and SI / decimal power (watts and prefixes) (Gigawatts). All linear values are mapped through watts first. The numeric factor is 2.930711e-10.
