Therm to Megajoule Converter
Convert therms to megajoules instantly. Free, bidirectional, and fully in-browser.
1 therm equals 105.4804 megajoules — enter any therm value to convert it to megajoules instantly. This Therm to Megajoule converter is a client-side tool: it applies a single multiplication (MJ = thm × 105.4804) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert megajoules back to therms. A reference table lists common therm values already converted, and nothing you enter is sent to a server.

Why use Therm to Megajoule Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to megajoule → therm without reloading.
Exact Energy math
The conversion uses the precise factor (MJ = thm × 105.4804), so the number matches a manual calculation to the decimal places you choose.
Adjustable precision
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Private and free
Everything runs locally in your browser — no upload, no account, no limit on conversions.
Common use cases
- Converting a therm measurement to megajoules for a spec, listing, or report.
- Checking therm↔megajoule figures while comparing products, datasets, or documentation.
- Learning the therm-to-megajoule relationship from the worked formula and the common-value table.
Frequently asked questions
How many megajoules are in a therm?
One therm is 105.4804 megajoules. Multiply the therm value by 105.4804 to convert. For example, 10 thm = 1054.804 MJ.
What is the formula to convert therms to megajoules?
MJ = thm × 105.4804. This tool applies it automatically and shows a worked example: 10 thm = 1054.804 MJ.
Can it convert megajoules back to therms?
Yes. Press the swap button, or type into the megajoule field, and the tool converts megajoules to therms using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard energy and work definition (MJ = thm × 105.4804), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
