Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (watt (W)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 cal (th)/s = 4.184 watt (W)
2. Target SI Bridge (ktarget):1 ft·lbf/s = 1.355818 watt (W)
Step-by-step substitution for Calorie (th)/second → Foot pound-force/second:V(ft·lbf/s) = V(cal (th)/s) × ( 4.184 / 1.355818 ) = V(cal (th)/s) × 3.08596

Frequently Asked Questions

There are exactly 3.08596003 foot pound forces/second (ft·lbf/s) in 1 calorie (th)/second (cal (th)/s). To calculate larger amounts manually, simply multiply your total number of calories (th)/second by the conversion multiplier of 3.08596003.

The mathematical formula to convert calories (th)/second to foot pound forces/second is: [value] * 3.08596003 = foot pound forces/second. Rather than doing the math manually, you can use our high-precision online calculator to process this exact equation instantly without rounding errors.

To perform the reverse calculation from foot pound forces/second back to calories (th)/second, you must divide your starting value by 3.08596003. Our bidirectional tool automatically computes this inverse equation the moment you type into the foot pound-force/second input field.

1 Calorie (th)/second is larger than 1 Foot pound-force/second. Specifically, 1 Calorie (th)/second equals exactly 3.08596003 foot pound forces/second, making it 3.086 times larger (a difference of 0.49 orders of magnitude). Therefore, quantities expressed in foot pound forces/second require a larger numerical value to represent the same physical amount.

A typical thermochemical calorie per second heat transfer rate (4.184 W) measures 1 cal_th/s, which corresponds to 3.086 Foot Pound Force Per Second (Foot pound-force/second).

There are exactly 3.08596 ft·lbf/s in 1 cal (th)/s. Since 1 ft·lbf/s equals roughly 1.35582 W, and 1 cal (th)/s = 4.184 W, the ratio is 1 cal (th)/s = 3.08596 ft·lbf/s.

Multiply the value in calories (th) per second by 3.08596 to obtain foot pound-force per second. The rigorous formula is V(ft·lbf/s) = V(cal (th)/s) × 3.08596.

For the reverse calculation, multiply the foot pound-force per second value by 0.324049. The inverse formula is V(cal (th)/s) = V(ft·lbf/s) × 0.324049.

A foot pound-force per second is the imperial mechanical power rate equivalent to displacing a one-pound mass vertically by one foot against standard Earth gravity in exactly one second.
