What is the exact conversion rate from horsepower to kilojoule per minute?

1 horsepower [hp, hp (UK)] equals approximately 44.7419922949 kilojoule per minute [kJ/min].

Can this tool convert metric horsepower to kilojoule per minute?

The tool is based on the common mechanical (imperial) horsepower; metric horsepower conversions may differ and are not directly supported.

Why use kilojoule per minute instead of watts for power conversion?

Kilojoule per minute is helpful for expressing energy transfer over minutes, useful in physiological and calorimetric measurements where minute-scale units are preferred.

What Is This Tool?

This converter allows you to transform power values from horsepower, an imperial unit commonly used to rate engines and motors, to kilojoule per minute, a metric unit measuring energy transfer over time. It facilitates comparison between mechanical power ratings and energy-based metrics.

How to Use This Tool?

Enter the power value in horsepower (hp, hp UK)
Select the target unit as kilojoule per minute (kJ/min)
Click convert to get the equivalent power expressed as kilojoule per minute

Key Features

Converts horsepower (hp, hp UK) to kilojoule/minute (kJ/min) accurately using a defined conversion rate
Supports conversions relevant to automotive, physiological, calorimetric, and industrial contexts
Browser-based and easy to use without requiring additional software

Examples

2 horsepower converts to approximately 89.48 kJ/min
0.5 horsepower converts to about 22.37 kJ/min

Common Use Cases

Comparing mechanical engine power output with energy rates in exercise physiology
Analyzing heating and cooling rates over minutes in laboratory calorimetry
Specifying power ratings for industrial machinery and small appliances

Tips & Best Practices

Confirm the variant of horsepower used, as different definitions exist
Use kilojoule per minute when energy transfer over minutes is the preferred time unit
Cross-check conversions when precise power measurement is required due to potential rounding

Limitations

The conversion rate applies specifically to the common mechanical (imperial) horsepower and may differ for metric variants
Kilojoule per minute assumes steady energy transfer; for variable power, smaller time-scale units like watts may be better
Measurement accuracy can be affected by rounding and differences between non-SI and SI units
