About Ton of Refrigeration (TR)
One ton of refrigeration (TR) equals 12,000 BTU/h (IT), approximately 3,516.85 W. It is widely used in HVAC and refrigeration sizing.
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.
How to convert tons of refrigeration (tr) to btu per hour (it)
1 ton of refrigeration (tr) is equal to 12000 btu per hour (it) when both are expressed in watt-equivalents:
1 tr = (3,516.8528420666667 W ÷ 0.2930710701722222 W) btu_hr = 12000 btu_hr
Each ton of refrigeration (tr) is defined as 3,516.8528420666667 W and each btu per hour (it) as 0.2930710701722222 W in this tool, so one tr equals 3,516.8528420666667 ÷ 0.2930710701722222 btu_hr = 12000 btu_hr.
Let d(tr) be the numeric value in Ton of Refrigeration (TR) (tr), and d(btu_hr) the value in BTU per Hour (IT) (btu_hr). Then:
d(btu_hr) = d(tr) × (3,516.8528420666667 / 0.2930710701722222)
Equivalently, divide by how many tr fit into one btu_hr (watts per btu_hr divided by watts per tr):
d(btu_hr) = d(tr) ÷ 0.00008333333333
Or: btu per hour (it) = ton of refrigeration (tr) ÷ 0.00008333333333
Examples
Example #1: Convert 1 tr to btu per hour (it)
1 tr = 1 tr × (3,516.8528420666667/0.2930710701722222) btu_hr = 12000 btu_hr
1 tr = 1 tr ÷ 0.00008333333333 = 12000 btu_hr
Intermediate watts: 3,516.85284207 W
Example #2: Convert 10 tr to btu per hour (it)
10 tr = 10 tr × (3,516.8528420666667/0.2930710701722222) btu_hr = 120000 btu_hr
10 tr = 10 tr ÷ 0.00008333333333 = 120000 btu_hr
Intermediate watts: 35,168.5284207 W
Summary
To convert Ton of Refrigeration (TR) to BTU per Hour (IT), multiply the value in tr by the ratio of watts per tr divided by watts per btu_hr. Equivalently: value_btu_hr = value_tr × (3516.8528420666667 / 0.2930710701722222). Numerically, 1 tr equals 12000 btu_hr.
Relationship context
You are converting between apparent power at unity PF (VA) (Tons of Refrigeration (TR)) and thermal engineering rates (BTU/h, kcal/h) (BTU per Hour (IT)). All linear values are mapped through watts first. The numeric factor is 1.200000e+4.
