What does one horsepower (metric) hour represent?

It represents the energy delivered by sustaining one metric horsepower (735.49875 watts) for one hour, equal to 2,647,795.5 joules.

What is a ton-hour (refrigeration)?

A ton-hour (refrigeration) quantifies the cooling effect produced by sustaining one refrigeration ton (heat removal rate of 12,000 BTU/h) for one hour.

Why convert between horsepower (metric) hour and ton-hour (refrigeration)?

Conversions allow translating engine work energy into equivalent refrigeration energy values, useful for comparing and integrating energy data across mechanical and cooling systems.

Key Features

Converts energy values from horsepower (metric) hour to ton-hour (refrigeration).
Provides conversion formulas and example calculations.
Supports understanding of energy unit relationships in mechanical and cooling applications.
Helps compare and translate energy data across different industries like automotive and refrigeration.

Examples

5 horsepower (metric) hours equals 1.045677461 ton-hour (refrigeration).
10 horsepower (metric) hours equals 2.091354922 ton-hour (refrigeration).

Common Use Cases

Estimating the energy produced by engines rated in metric horsepower over time.
Sizing and reporting cooling energy removed by commercial chillers and HVAC systems.
Specifying thermal energy storage capacity such as ice or chilled-water in refrigeration systems.
Converting engine work data to refrigeration energy for energy efficiency and load management.
Engineering cold storage, refrigerated transport, and large supermarket refrigeration systems.

Tips & Best Practices

Use the conversion tool as an analytical aid to compare mechanical and refrigeration energy outputs.
Remember the differences in physical energy types when interpreting conversion results.
Consider system efficiencies and environmental factors when applying theoretical conversions to real scenarios.
Double-check unit selections before converting to ensure accurate results.
Use example calculations to verify your conversion results.

Limitations

The units represent different physical energy forms—mechanical work versus heat removal—so conversions are approximate comparisons.
Actual energy use may differ due to varying system efficiencies and environmental conditions.
Conversions are intended for comparative or analytical purposes, not direct equivalence of function.
