How to Convert Ton Of Refrigeration to Btu/hour

1 ton of refrigeration = 12000 Btu/hour

Btu/hour = Ton Of Refrigeration × 12000

Example: 1 TR × 12000 = 12000 Btu/h

Reverse Conversion

To convert Btu/hour back to tons of refrigeration:

  • Remember, 1 Btu/hour equals 8.33333 × 10-5 tons of refrigeration.
  • To convert 12000 Btu/h to TR, multiply 12000 x 8.33333 × 10-5, resulting in 1 TR.

About the Ton Of Refrigeration

Facts & Uses

  • Industry-standard cooling power unit for refrigeration and air conditioning.
  • 1 TR = 12,000 Btu/h = 3.5168525 kW.
  • Used globally to rate chillers, cooling towers, and A/C systems.

Curiosities

  • Originates from the heat needed to freeze one short ton (2000 lb) of water in 24 hours.
  • 1 ton of cooling ≈ 3.5 kW, roughly equal to a medium home A/C system.

About the Btu/hour

Facts & Uses

  • Standard power rating in HVAC (heating, ventilation, air conditioning) systems.
  • Air conditioners and furnaces are often rated in Btu/h or tons of refrigeration (1 ton = 12,000 Btu/h).
  • Useful for comparing cooling capacities or fuel efficiencies.

Curiosities

  • 1 Btu/h = 0.293071 W — a 12,000 Btu/h air conditioner is roughly 3.52 kW.
  • MBH (1000 Btu/h) is a common shorthand in U.S. equipment specs.

Frequently Asked Questions

How many Btu/hour are in one ton of refrigeration?

One ton of refrigeration equals 12000 Btu/hour. To convert, multiply the ton of refrigeration value by 12000. For the reverse, divide the Btu/hour value by 12000 (or multiply by 8.33333 × 10-5).

What is 5 tons of refrigeration in Btu/hour?

5 tons of refrigeration = 60000 Btu/hour. This is one of the most commonly searched conversions for this pair.

How precise is the ton of refrigeration-to-Btu/hour conversion?

The factor 12000 is accurate to 6 significant figures, derived from international measurement standards. Our calculator uses full precision internally.
