About Kilocalorie per Hour (thermochemical)
Kilocalories per hour is a thermal power rate using the thermochemical kilocalorie (4,184 J per kcal) spread over one hour.
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 kilocalories per hour (thermochemical) to foot-pounds per second
1 kilocalorie per hour (thermochemical) is equal to 0.85721112016002 foot-pound per second when both are expressed in watt-equivalents:
1 kcal_h = (1.1622222222222223 W ÷ 1.3558179483314003 W) ft_lb_s = 0.85721112016002 ft_lb_s
Each kilocalorie per hour (thermochemical) is defined as 1.1622222222222223 W and each foot-pound per second as 1.3558179483314003 W in this tool, so one kcal_h equals 1.1622222222222223 ÷ 1.3558179483314003 ft_lb_s = 0.85721112016002 ft_lb_s.
Let d(kcal_h) be the numeric value in Kilocalorie per Hour (thermochemical) (kcal_h), and d(ft_lb_s) the value in Foot-pound per Second (ft_lb_s). Then:
d(ft_lb_s) = d(kcal_h) × (1.1622222222222223 / 1.3558179483314003)
Equivalently, divide by how many kcal_h fit into one ft_lb_s (watts per ft_lb_s divided by watts per kcal_h):
d(ft_lb_s) = d(kcal_h) ÷ 1.16657376051459
Or: foot-pound per second = kilocalorie per hour (thermochemical) ÷ 1.16657376051459
Examples
Example #1: Convert 1 kcal_h to foot-pound per second
1 kcal_h = 1 kcal_h × (1.1622222222222223/1.3558179483314003) ft_lb_s = 0.8572111202 ft_lb_s
1 kcal_h = 1 kcal_h ÷ 1.16657376051459 = 0.8572111202 ft_lb_s
Intermediate watts: 1.1622222222 W
Example #2: Convert 10 kcal_h to foot-pound per second
10 kcal_h = 10 kcal_h × (1.1622222222222223/1.3558179483314003) ft_lb_s = 8.5721112016 ft_lb_s
10 kcal_h = 10 kcal_h ÷ 1.16657376051459 = 8.5721112016 ft_lb_s
Intermediate watts: 11.6222222222 W
Summary
To convert Kilocalorie per Hour (thermochemical) to Foot-pound per Second, multiply the value in kcal_h by the ratio of watts per kcal_h divided by watts per ft_lb_s. Equivalently: value_ft_lb_s = value_kcal_h × (1.1622222222222223 / 1.3558179483314003). Numerically, 1 kcal_h equals 0.8572111201600218 ft_lb_s.
