How to Convert Fuel Efficiency Volume Units

This converter uses joule per cubic meter (J/m³) as an intermediate unit. The conversion factors are:

• \( 1 \, \text{J/L} = 1000 \, \text{J/m³} \)
• \( 1 \, \text{MJ/m³} = 1,000,000 \, \text{J/m³} \)
• \( 1 \, \text{kJ/m³} = 1000 \, \text{J/m³} \)
• \( 1 \, \text{kcal/m³} = 4186.8 \, \text{J/m³} \)
• \( 1 \, \text{cal/cm³} = 4,186,800 \, \text{J/m³} \)
• \( 1 \, \text{therm/galUK} = \frac{105,505,585.257}{0.00454609} \, \text{J/m³} \approx 23,200,000,000 \, \text{J/m³} \)
• \( 1 \, \text{Btu(IT)/ft³} = \frac{1055.05585262}{0.028316846592} \, \text{J/m³} \approx 37,258.947 \, \text{J/m³} \)
• \( 1 \, \text{Btu(th)/ft³} = \frac{1054.35}{0.028316846592} \, \text{J/m³} \approx 37,236.374 \, \text{J/m³} \)
• \( 1 \, \text{CHU/ft³} = \frac{1899.100534716}{0.028316846592} \, \text{J/m³} \approx 67,066.105 \, \text{J/m³} \)
• \( 1 \, \text{m³/J} = \frac{1}{\text{J/m³}} \)
• \( 1 \, \text{L/J} = \frac{1000}{\text{J/m³}} \)
• \( 1 \, \text{galUS/(hp·h)} = \frac{\frac{2,684,520}{0.00378541}}{\text{J/m³}} \approx \frac{709,175,035.87}{\text{J/m³}} \)

Enter a value, select the units, and click "Convert" to see the result.

Example Conversion

Convert 1000 J/m³ to Btu(IT)/ft³:

1. Input: 1000 J/m³
2. Conversion: \( 1000 \div \frac{1055.05585262}{0.028316846592} \approx 1000 \div 37,258.947 \approx 0.026839 \, \text{Btu(IT)/ft³} \)
3. Result: 0.026839 Btu(IT)/ft³

Common Conversion Table

Note: For volume per energy units (e.g., m³/J, L/J, galUS/(hp·h)), the values represent conversions from 1 J/m³ and may result in large numbers due to the inverse relationship.
