Convert BTU / second to (foot • pound) / second

Learn how to convert 1 BTU / second to (foot • pound) / second step by step.

Calculation Breakdown

Set up the equation
\(1.0\left(\dfrac{BTU}{second}\right)={\color{rgb(20,165,174)} x}\left(\dfrac{foot \times pound}{second}\right)\)
Define the base values of the selected units in relation to the SI unit \(\left(watt\right)\)
\(\text{Left side: 1.0 } \left(\dfrac{BTU}{second}\right) = {\color{rgb(89,182,91)} 1054.5\left(watt\right)} = {\color{rgb(89,182,91)} 1054.5\left(W\right)}\)
\(\text{Right side: 1.0 } \left(\dfrac{foot \times pound}{second}\right) = {\color{rgb(125,164,120)} 1.3558180656\left(watt\right)} = {\color{rgb(125,164,120)} 1.3558180656\left(W\right)}\)
Insert known values into the conversion equation to determine \({\color{rgb(20,165,174)} x}\)
\(1.0\left(\dfrac{BTU}{second}\right)={\color{rgb(20,165,174)} x}\left(\dfrac{foot \times pound}{second}\right)\)
\(\text{Insert known values } =>\)
\(1.0 \times {\color{rgb(89,182,91)} 1054.5} \times {\color{rgb(89,182,91)} \left(watt\right)} = {\color{rgb(20,165,174)} x} \times {\color{rgb(125,164,120)} {\color{rgb(125,164,120)} 1.3558180656}} \times {\color{rgb(125,164,120)} \left(watt\right)}\)
\(\text{Or}\)
\(1.0 \cdot {\color{rgb(89,182,91)} 1054.5} \cdot {\color{rgb(89,182,91)} \left(W\right)} = {\color{rgb(20,165,174)} x} \cdot {\color{rgb(125,164,120)} 1.3558180656} \cdot {\color{rgb(125,164,120)} \left(W\right)}\)
\(\text{Cancel SI units}\)
\(1.0 \times {\color{rgb(89,182,91)} 1054.5} \cdot {\color{rgb(89,182,91)} \cancel{\left(W\right)}} = {\color{rgb(20,165,174)} x} \times {\color{rgb(125,164,120)} 1.3558180656} \times {\color{rgb(125,164,120)} \cancel{\left(W\right)}}\)
\(\text{Conversion Equation}\)
\(1054.5 = {\color{rgb(20,165,174)} x} \times 1.3558180656\)
Switch sides
\({\color{rgb(20,165,174)} x} \times 1.3558180656 = 1054.5\)
Isolate \({\color{rgb(20,165,174)} x}\)
Multiply both sides by \(\left(\dfrac{1.0}{1.3558180656}\right)\)
\({\color{rgb(20,165,174)} x} \times 1.3558180656 \times \dfrac{1.0}{1.3558180656} = 1054.5 \times \dfrac{1.0}{1.3558180656}\)
\(\text{Cancel}\)
\({\color{rgb(20,165,174)} x} \times {\color{rgb(255,204,153)} \cancel{1.3558180656}} \times \dfrac{1.0}{{\color{rgb(255,204,153)} \cancel{1.3558180656}}} = 1054.5 \times \dfrac{1.0}{1.3558180656}\)
\(\text{Simplify}\)
\({\color{rgb(20,165,174)} x} = \dfrac{1054.5}{1.3558180656}\)
Solve \({\color{rgb(20,165,174)} x}\)
\({\color{rgb(20,165,174)} x}\approx777.75921914\approx7.7776 \times 10^{2}\)
\(\text{Conversion Equation}\)
\(1.0\left(\dfrac{BTU}{second}\right)\approx{\color{rgb(20,165,174)} 7.7776 \times 10^{2}}\left(\dfrac{foot \times pound}{second}\right)\)
