What is horsepower (boiler)?

Horsepower (boiler) is a thermal power unit representing the rate of heat needed to evaporate 34.5 pounds of water per hour at 212°F, often used to express steam boiler capacity.

How does horsepower [hp, hp (UK)] differ?

Horsepower [hp, hp (UK)] is a non-SI unit measuring mechanical power as work done per second, typically defined as 550 foot‑pounds per second.

Can I directly compare horsepower (boiler) and mechanical horsepower?

While this converter translates the units, the types of power differ: thermal for boilers and mechanical for engines, so comparisons should consider their distinct meanings.

How to Convert from Horsepower (boiler) to Horsepower [hp, hp (UK)]?

Easily convert power values from horsepower (boiler), a unit of thermal power used in steam boilers, to the mechanical horsepower [hp, hp (UK)] used for engines and motors with this tool.

Key Features

Converts steam boiler thermal power units to mechanical horsepower
Supports accurate translation between horsepower (boiler) and hp (UK)
Facilitates comparison of boiler output with engine power ratings
Browser-based and easy to use for engineering and industrial purposes

Examples

Converting 2 horsepower (boiler) yields approximately 26.31 horsepower [hp, hp (UK)].
For 0.5 horsepower (boiler), the equivalent is about 6.58 horsepower [hp, hp (UK)].

Common Use Cases

Rating industrial steam boilers and indicating their steaming capacity.
Sizing and comparing steam-generation equipment in manufacturing or power plants.
Translating boiler thermal power to mechanical power for engine and motor specifications.
Assessing historical marine and locomotive boiler outputs against modern mechanical units.

Tips & Best Practices

Always confirm the specific horsepower variant used in the comparison to avoid confusion.
Use conversions to assist in integrating thermal and mechanical power measurements.
Remember that direct conversion translates units but involves different physical power types.

Limitations

Horsepower (boiler) reflects thermal power for steam production, whereas horsepower [hp, hp (UK)] measures mechanical work rate.
Converting between these units does not imply identical physical meanings but rather unit equivalence.
Consider variations in horsepower definitions and ensure consistent use when comparing values.
