What does one therm represent?

One therm is a non-SI energy unit used mostly for natural gas, defined as 100,000 British thermal units (BTU), which corresponds roughly to 1.055×10^8 joules.

How is a metric horsepower hour defined?

A metric horsepower hour is the energy from sustaining one metric horsepower (735.49875 watts) for one hour, equal to about 2,647,795.5 joules.

Why convert therms to metric horsepower hours?

Converting helps compare the energy content of natural gas to the energy output of engines rated in metric horsepower, useful in fuel efficiency and performance analysis.

Examples

Convert 2 therms: 2 × 39.8465818074 = 79.6931636148 horsepower (metric) hour.
Convert 0.5 therm: 0.5 × 39.8465818074 = 19.9232909037 horsepower (metric) hour.

Common Use Cases

Billing and tariffs for natural gas by translating consumption to engine energy use.
Estimating energy output of engines rated in metric horsepower over specific durations.
Converting between natural gas energy content and engine work for efficiency checks.
Interpreting historical or industrial records listing energy in metric horsepower hours.

Tips & Best Practices

Verify the definition of therm used in your region due to variations in BTU standards.
Ensure steady-state power assumptions align with your context when using metric horsepower hour results.
Use consistent units and conversion methods for industrial or research energy calculations.
Cross-check results when comparing with purely SI-based energy units to avoid discrepancies.

Limitations

Variations in the exact therm value based on differing BTU definitions affect conversion accuracy.
Metric horsepower hour is not an SI unit, which may complicate integration with SI-only data.
Assumes a constant power output over the hour; transient loads may require more detailed assessment.
