How much CO₂ is produced by burning 1 liter of gasoline?

Burning 1 liter of gasoline generates approximately 2.31 kg of CO₂. Although 1 liter of gasoline weighs only ~0.74 kg, the carbon atoms combine with atmospheric oxygen (molecular weight increases from 12 to 44) during combustion, producing over 3 times the fuel's original weight in CO₂.

How do you calculate total fuel required for a road trip?

Fuel (Liters) = Distance (km) / Fuel Economy (km/L). In US units, Gallons = Distance (miles) / MPG. A vehicle getting 30 MPG traveling 600 miles requires 600 / 30 = 20 gallons of fuel (75.7 liters).

How to Convert Miles per gallon (UK) to Miles per liter

Converting Miles per gallon (UK) (mpg (UK)) to Miles per liter (mi/L) is a core calculation in Fuel Economy, which measures the vehicular travel distance achieved per unit volume of consumed liquid or gaseous fuel. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Miles per gallon (UK) equals 0.219969 Miles per liter, while 1 mi/L equals 4.54609 mpg (UK).

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (kilometer per liter (km/L)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 mpg (UK) = 2.824809 kilometer per liter (km/L)

2. Target SI Bridge (k_target):1 mi/L = 0.621371 kilometer per liter (km/L)

Step-by-step substitution for Miles per gallon (UK) → Miles per liter:V(mi/L) = V(mpg (UK)) × ( 2.824809 / 0.621371 ) = V(mpg (UK)) × 0.219969
