What is a foot-pound unit?

A foot-pound (ft·lbf) is an imperial unit of energy representing the work done by a one pound-force acting over one foot.

What does horsepower hour measure?

Horsepower hour (hp·h) quantifies the energy produced by delivering one horsepower of power continuously over one hour.

Why do converted values from foot-pound to horsepower hour become very small?

Because foot-pound measures small mechanical energy and horsepower hour measures larger continuous power, conversions yield very small decimal numbers.

How to Convert from Foot-pound [ftlbf] to Horsepower hour [hph]

Convert energy values from foot-pound (ft*lbf), an imperial unit for small mechanical work, to horsepower hour (hp*h), a unit measuring continuous mechanical power over time.

What Is This Tool?

This converter allows you to change energy measurements from foot-pound (ft·lbf) used for small-scale mechanical work into horsepower hour (hp·h), which expresses larger continuous mechanical energy output over time.

How to Use This Tool?

Enter the energy value in foot-pound units.
Select 'foot-pound [ft*lbf]' as the input unit.
Choose 'horsepower hour [hp*h]' as the output unit.
Initiate conversion to see equivalent energy in horsepower hours.

Key Features

Converts energy between foot-pound and horsepower hour units.
Provides straightforward calculation using a set conversion factor.
Supports energy quantification for mechanical and automotive applications.

Examples

Converting 10 foot-pound results in approximately 5.0505e-6 horsepower hours.
Converting 1,000,000 foot-pound equals about 0.50505 horsepower hours.

Common Use Cases

Assessing small mechanical work or energy with foot-pound units.
Estimating continuous engine or motor output using horsepower hours.
Comparing mechanical work to electrical energy in legacy equipment ratings.

Tips & Best Practices

Use this converter for translating small mechanical energy into larger-scale continuous power units.
Be cautious about slight variations in horsepower definitions which can influence accuracy.
Remember hp·h approximates electrical energy units but is not an exact match.

Limitations

Foot-pound units are for small energy amounts while horsepower hours represent larger, continuous outputs, resulting in very small decimal conversions.
Different horsepower definitions (mechanical vs metric) can cause minor differences in energy equivalences.
Hp·h approximates but is not identical to electrical energy units such as kilowatt-hours.

Frequently Asked Questions

What is a foot-pound unit?: A foot-pound (ft·lbf) is an imperial unit of energy representing the work done by a one pound-force acting over one foot.
What does horsepower hour measure?: Horsepower hour (hp·h) quantifies the energy produced by delivering one horsepower of power continuously over one hour.
Why do converted values from foot-pound to horsepower hour become very small?: Because foot-pound measures small mechanical energy and horsepower hour measures larger continuous power, conversions yield very small decimal numbers.

Key Terminology

Foot-pound [ft*lbf]: An imperial unit of energy equal to the work done by a one pound-force over a distance of one foot.
Horsepower hour [hp*h]: A unit of energy representing the power of one horsepower delivered continuously for one hour.
Mechanical horsepower: A standard horsepower definition approximately equal to 745.699872 watts, often used for calculating hp·h.

Quick Knowledge Check

What does the foot-pound unit measure?

Electrical energy output

Mechanical energy from force over distance

Continuous engine power

How is one horsepower hour defined?

Energy from one horsepower in one hour

Force acting over one foot

Electrical power usage per second

Why should hp·h be used carefully in electrical contexts?

Because it is not a unit of energy

Because it only approximates electrical energy units like kilowatt-hours

Because it is only used in automotive repair
