Unit conversion relations

$1 \; Kilowatt = 1.34 \; Imperial\; Horsepower = 1.36 \; Metric\; Horsepower \\[12pt] 1 \; \text{kW} = 1.34 \; \text{HP} = 1.36 \; \text{PS}$

$1 \; kilowatt = 860 \; kilocalories\; per\; hour = 0.24 \; kilocalories\; per\; second \\[12pt] 1 \; \text{kW} = 860 \; \text{kcal/h} = 0.24 \; \text{kcal/s}$

$1 \; kilowatt = 3412 \; BTU\; per\; hour = 0.95 \; BTU\; per\; second \\[12pt] 1 \; \text{kW} = 3412 \; \text{BTU/h} = 0.95 \; \text{BTU/s}$

$1 \; kilowatt = 102 \; kilogram-force-meter per second = 738 \; pound-force-feet per second \\[12pt] 1 \; \text{kW} = 102 \; \text{kgf} \cdot \text{m/s} = 738 \; \text{lbf} \cdot \text{ft/s}$
