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 Volt-Ampere (VA)
Volt-amperes describe apparent power in AC circuits. At unity power factor, VA matches real power in watts; this tool uses that 1:1 mapping for conversion.
How to convert btu per hour (it) to volt-amperes (va, unity pf)
1 btu per hour (it) is equal to 0.29307107017222 volt-ampere (va) when both are expressed in watt-equivalents:
1 btu_hr = (0.2930710701722222 W ÷ 1 W) va = 0.29307107017222 va
Each btu per hour (it) is defined as 0.2930710701722222 W and each volt-ampere (va) as 1 W in this tool, so one btu_hr equals 0.2930710701722222 ÷ 1 va = 0.29307107017222 va.
Let d(btu_hr) be the numeric value in BTU per Hour (IT) (btu_hr), and d(va) the value in Volt-Ampere (VA) (va). Then:
d(va) = d(btu_hr) × (0.2930710701722222 / 1)
Equivalently, divide by how many btu_hr fit into one va (watts per va divided by watts per btu_hr):
d(va) = d(btu_hr) ÷ 3.41214163312794
Or: volt-ampere (va) = btu per hour (it) ÷ 3.41214163312794
Examples
Example #1: Convert 1 btu_hr to volt-ampere (va)
1 btu_hr = 1 btu_hr × (0.2930710701722222/1) va = 0.2930710702 va
1 btu_hr = 1 btu_hr ÷ 3.41214163312794 = 0.2930710702 va
Intermediate watts: 0.2930710702 W
Example #2: Convert 10 btu_hr to volt-ampere (va)
10 btu_hr = 10 btu_hr × (0.2930710701722222/1) va = 2.9307107017 va
10 btu_hr = 10 btu_hr ÷ 3.41214163312794 = 2.9307107017 va
Intermediate watts: 2.9307107017 W
Summary
To convert BTU per Hour (IT) to Volt-Ampere (VA), multiply the value in btu_hr by the ratio of watts per btu_hr divided by watts per va. Equivalently: value_va = value_btu_hr × (0.2930710701722222 / 1). Numerically, 1 btu_hr equals 0.2930710701722222 va.
Relationship context
You are converting between thermal engineering rates (BTU/h, kcal/h) (BTU per Hour (IT)) and apparent power at unity PF (VA) (Volt-Amperes (VA, unity PF)). All linear values are mapped through watts first. The numeric factor is 2.930711e-1.
