Example value from the reference table. Internal calculation uses stored factors; display output is rounded.

02Common mistake

PS and hp are not identical. Vehicle data often uses metric horsepower, while US/UK contexts often use mechanical horsepower.

03Base unit: W

1 BTU/h = 0.293071070172 W. Then the value is converted through the base unit W into Kilowatt.
