What is a millijoule?

A millijoule (mJ) is an SI derived unit of energy equal to 0.001 joules, commonly used to quantify very small amounts of energy in scientific and engineering fields.

What does the US therm measure?

The US therm is a non-SI unit of heat energy equal to 100,000 British thermal units, often used in the United States for measuring natural gas and heating energy.

Why convert millijoules to therm (US)?

Converting millijoules to therm (US) helps relate very small scientific energy values to practical large-scale energy units used in residential and industrial heating and gas billing.

Helps relate very small energy measurements to large-scale practical heating units.

Examples

Convert 1000 mJ to therm (US): 1000 mJ × 9.4804342797336e-12 = 9.48043428e-9 therm (US).
Convert 5000 mJ to therm (US): 5000 mJ × 9.4804342797336e-12 = 4.74021714e-8 therm (US).

Common Use Cases

Specifying pulse energy of low-power lasers and LEDs in scientific experiments.
Quantifying energy from small electronic or capacitor discharge events in microelectronics.
Relating tiny energy measurements to natural gas billing and heating system energy ratings.
Estimating fuel energy content for industrial processes and emissions accounting.
Designing and evaluating heating systems or energy consumption in residential and commercial buildings.

Tips & Best Practices

Ensure input values are accurate to avoid errors especially given the very small conversion factor.
Use this conversion mainly to understand the scale difference between scientific and commercial energy units.
Double-check results when converting very small energies to large units to manage precision limitations.
Refer to examples provided to confirm correct usage of the tool.
Understand the context of your conversion to interpret results effectively, especially in industrial or research settings.

Limitations

The conversion factor is extremely small, so millijoule values yield negligible therm (US) amounts.
This conversion is mainly theoretical or for illustrative comparisons rather than practical energy billing.
Precision issues can arise when converting small-scale energies into much larger units like therm (US).
