The power of 1 metric horsepower corresponds to 735.49875 watts.
\(W = PS · 735,49875\)
\(\displaystyle PS=\frac{W}{735.49875}\)
The power of 1 horsepower corresponds to 745.70 watts.
\(W = hp · 745,7\)
\(\displaystyle hp=\frac{W}{745.7}\)
The power of 1 calories / second corresponds to 4.1868 watts.
\(W = cal/s · 4.1868\)
\(\displaystyle cal/s=\frac{W}{4.1868}\)
The power of 1 BTU / second corresponds to 1055.05585262 watts.
\(W = BTU/s · 1055.05585262\)
\(\displaystyle BTU/s=\frac{W}{1055.05585262}\)
