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 Foot-pound per Second
Foot-pounds per second is a mechanical power rate: 1 ft·lb/s = 1.3558179483314004 W (exactly, from the international foot definition).
How to convert tons of refrigeration (tr) to foot-pounds per second
1 ton of refrigeration (tr) is equal to 2593.8975408865499 foot-pound per second when both are expressed in watt-equivalents:
1 tr = (3,516.8528420666667 W ÷ 1.3558179483314003 W) ft_lb_s = 2593.8975408865499 ft_lb_s
Each ton of refrigeration (tr) is defined as 3,516.8528420666667 W and each foot-pound per second as 1.3558179483314003 W in this tool, so one tr equals 3,516.8528420666667 ÷ 1.3558179483314003 ft_lb_s = 2593.8975408865499 ft_lb_s.
Let d(tr) be the numeric value in Ton of Refrigeration (TR) (tr), and d(ft_lb_s) the value in Foot-pound per Second (ft_lb_s). Then:
d(ft_lb_s) = d(tr) × (3,516.8528420666667 / 1.3558179483314003)
Equivalently, divide by how many tr fit into one ft_lb_s (watts per ft_lb_s divided by watts per tr):
d(ft_lb_s) = d(tr) ÷ 0.00038552023904
Or: foot-pound per second = ton of refrigeration (tr) ÷ 0.00038552023904
Examples
Example #1: Convert 1 tr to foot-pound per second
1 tr = 1 tr × (3,516.8528420666667/1.3558179483314003) ft_lb_s = 2593.89754089 ft_lb_s
1 tr = 1 tr ÷ 0.00038552023904 = 2593.89754089 ft_lb_s
Intermediate watts: 3,516.85284207 W
Example #2: Convert 10 tr to foot-pound per second
10 tr = 10 tr × (3,516.8528420666667/1.3558179483314003) ft_lb_s = 25938.9754089 ft_lb_s
10 tr = 10 tr ÷ 0.00038552023904 = 25938.9754089 ft_lb_s
Intermediate watts: 35,168.5284207 W
Summary
To convert Ton of Refrigeration (TR) to Foot-pound per Second, multiply the value in tr by the ratio of watts per tr divided by watts per ft_lb_s. Equivalently: value_ft_lb_s = value_tr × (3516.8528420666667 / 1.3558179483314003). Numerically, 1 tr equals 2593.89754088655 ft_lb_s.
Relationship context
