What is the mechanical horsepower used in this conversion?

It is the common mechanical horsepower defined as 550 foot-pounds per second, approximately equal to 745.7 watts.

Why convert horsepower to pound-foot per hour?

To express power in legacy imperial units suitable for historical equipment, low-rate mechanical outputs, or specialized engineering calculations.

Can I use this conversion for metric horsepower?

No, this conversion is specific to the common mechanical horsepower and may not be accurate for other variants like metric horsepower.

What kind of equipment uses pound-foot per hour as a power unit?

Small clocks, gear-train devices, hand-cranks, slow winches, and vintage or historical mechanical machinery often use this unit.

What Is This Tool?

This converter transforms power measures from the common mechanical horsepower unit into pound-foot per hour, an imperial unit representing small continuous mechanical power output in legacy systems.

How to Use This Tool?

Enter the power value in horsepower (hp, hp UK) in the input field
Select horsepower as the input unit and pound-foot/hour as the output unit
Click the convert button to get the equivalent power in pound-foot/hour
Review the results which show the mechanical power rate in legacy imperial units

Key Features

Converts horsepower (hp, hp UK) to pound-foot/hour (lbf*ft/h) values
Uses the standard mechanical horsepower definition of 550 foot-pounds per second
Ideal for power ratings in automotive, industrial, and vintage equipment contexts
Browser-based and straightforward interface for fast calculations

Examples

1 hp = 1,980,000 lbf*ft/h
0.5 hp = 990,000 lbf*ft/h

Common Use Cases

Translating engine power ratings from modern horsepower units to historical imperial measurements
Documenting specifications of vintage or legacy equipment using foot-pound units
Estimating low continuous mechanical outputs such as small clocks or gear-train machinery
Converting power ratings for hand-crank or slow winch mechanisms

Tips & Best Practices

Ensure the horsepower value corresponds to the common mechanical horsepower definition before converting
Use this conversion primarily for low-power and historical equipment to avoid large numeric outputs
Cross-check unit definitions when dealing with other horsepower variants like metric horsepower
Use the tool for engineering contexts such as automotive comparisons and mechanical device specifications

Limitations

Conversion applies accurately only to the common mechanical horsepower definition, not other variants
Pound-foot per hour units are suited for very low mechanical power outputs and yield large values for higher horsepower
This unit is uncommon in modern high-power applications and mainly relevant for historical or specialized cases
