How to convert kilojoules to therms
Multiply by 0.000009478171 — one kilojoule is 0.000009478171 therms. That factor is exact: it comes from the definition of the units rather than from a measurement, so it will not change and does not need rounding.
Working 3 ÷ 105,505.59 = 0.000028434514
What these units are
The kilojoule and the therm are covered in the energy unit guide, along with every other unit on this page.
Questions
How many therms are in a kilojoule?
One kilojoule is 0.000009478171 therms. This figure is exact — it comes from the definition of the unit, not a measurement.
What is 3 kilojoules in therms?
3 kilojoules is 0.000028434514 therms. The working is 3 ÷ 105,505.59 = 0.000028434514.
Is a food Calorie the same as a calorie?
No — it is a thousand of them. The Calorie on a nutrition label is a kilocalorie, written with a capital C in principle and almost never in practice. A 250 Calorie chocolate bar holds 250,000 physics calories, or about 1,046 kilojoules, which is why European labels quote kJ alongside.
What does a kilowatt-hour actually represent?
One kilowatt drawn for one hour — a 1,000 W heater running for sixty minutes, or a 100 W bulb for ten hours. It is the unit your electricity bill is priced in, and it equals exactly 3.6 million joules.
How much energy is one BTU?
Roughly the heat needed to raise one pound of water by one degree Fahrenheit — about 1,055 joules, or the energy in a single kitchen match. Air conditioners are rated in BTU per hour, where a 12,000 BTU/h unit is one "ton" of cooling and draws around 3.5 kW of heat.
Why is the electronvolt so small?
Because it is sized for single particles: it is the energy one electron picks up crossing a one-volt potential difference. At about 1.6 × 10⁻¹⁹ joules it would be absurd for anything larger, which is precisely why particle physics uses it instead of dragging around twenty leading zeros.
