Examples

010.5 kW = 1,706.070817 BTU/h

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 kW = 1000 W. Then the value is converted through the base unit W into BTU per hour.
