How to Convert Therms to Joules (Step-by-Step)
Converting therms to joules bridges US gas billing (therms) with the SI energy system (joules). The conversion factor is 1 therm = 105,506,000 J (approximately 105.5 MJ). This comes from 1 therm = 100,000 BTU × 1055.06 J/BTU.
- Identify the gas usage in therms from your utility bill.
- Multiply by 105,506,000 to get joules (or by 105.506 for MJ).
- For practical use, express in MJ or GJ rather than raw joules.
- The conversion is: therms × 100,000 × 1055.06 = joules.

Solved Examples: Therms to Joules
Question 1: A household used 75 therms last month. Express in joules and GJ.
Solution:
Start with 75 therms.
Multiply by 105,506,000: 75 × 105,506,000 = 7,912,950,000 J.
Convert to GJ: 7,912,950,000 ÷ 10⁹ = 7.91 GJ.
Answer: 75 therms = 7.91 × 10⁹ J = 7.91 GJ
Question 2: Annual natural gas consumption is 850 therms. Convert to GJ for energy audit.
Solution:
Start with 850 therms.
Multiply by 105.506 MJ: 850 × 105.506 = 89,680 MJ.
Convert to GJ: 89,680 ÷ 1000 = 89.68 GJ.
Answer: 850 therms = 89.68 GJ/year
Question 3: A gas dryer uses 0.15 therms per load. How many MJ is that?
Solution:
Start with 0.15 therms.
Multiply by 105.506: 0.15 × 105.506 = 15.83 MJ.
Answer: 0.15 therms = 15.83 MJ per dryer load
Practice: Therms to Joules
Try solving these on your own to test your understanding:
- Convert 3 therms to MJ. (Answer: 316.5 MJ)
- Monthly gas use is 42 therms. Express in GJ. (Answer: 4.43 GJ)
- Convert 0.5 therms to joules. (Answer: 52,753,000 J)
- Annual gas consumption: 1,200 therms. Express in GJ. (Answer: 126.6 GJ)
- A gas range uses 0.02 therms per hour. Convert to MJ/hr. (Answer: 2.11 MJ/hr)
Energy Audits: Converting Gas Bills to SI Units
Professional energy audits and building performance certificates typically express energy in SI units (GJ or kWh). To convert annual gas usage: multiply therms by 0.1055 for GJ, or by 29.3 for kWh. For example, a home using 900 therms/year consumes 94.9 GJ or 26,370 kWh of gas energy. Combined with electricity usage (in kWh), this gives total site energy for efficiency ratings like Energy Star or HERS scores.
International Gas Billing: Therms vs Cubic Meters
While the US bills in therms, many countries bill natural gas in cubic meters (m³) or GJ. Approximate equivalences: 1 therm ≈ 2.83 m³ of natural gas (at standard conditions). 1 GJ ≈ 9.48 therms. The UK uses therms on bills but increasingly shows kWh equivalents. Australia bills directly in MJ. These differences mean international energy comparisons require careful unit conversion.
Carbon Emissions from Gas Usage
Each therm of natural gas burned produces approximately 5.3 kg of CO₂. Knowing the joule equivalent helps calculate carbon intensity: 105.5 MJ per therm with 5.3 kg CO₂ gives approximately 50 g CO₂ per MJ (or 0.05 kg/MJ). This carbon intensity factor is used in climate reporting and when comparing natural gas with other energy sources for environmental impact assessments.
Key Takeaways
- Multiply therms by 105,506,000 (or 105.506 MJ) to get joules.
- 1 therm = 105.5 MJ = 0.1055 GJ ≈ 29.3 kWh.
- Annual household gas (900 therms) ≈ 95 GJ.
- For energy audits, use GJ as the standard reporting unit.
- Each therm ≈ 5.3 kg CO₂ emissions from combustion.
- International equivalence: 1 therm ≈ 2.83 m³ of natural gas.
