Tons of refrigeration to BTU per hour (TR to BTU/h)

Formula

1 TR = 12000 BTU/h

BTU per hour = tons of refrigeration × 12000 — reverse: tons of refrigeration = BTU per hour × 0.00008333333333

The factor is derived from the SI definitions of both units (base unit: W) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.

Worked examples

• 5 TR = 60000 BTU/h
• 12.5 TR = 150000 BTU/h
• 100 TR = 1200000 BTU/h
