Conversion Formula

The formula to convert mpg to liters per 100 km multiplies 100 by the reciprocal of mpg, then adjusts for unit differences. The calculation: liters/100km = 100 * (1 / mpg) * (3.78541 / 1.60934). This works because it converts miles to kilometers and gallons to liters, standardizing units for comparison.

For example, to convert 25 mpg: 100 * (1 / 25) * (3.78541 / 1.60934) = 4 * 2.35215 = 9.4086 liters per 100 km.

Conversion Example

• Convert 20 mpg:
  • Step 1: Take reciprocal: 1 / 20 = 0.05
  • Step 2: Multiply by 100: 0.05 * 100 = 5
  • Step 3: Adjust for units: 5 * (3.78541 / 1.60934) ≈ 5 * 2.35215 = 11.76075 liters per 100 km
• Convert 30 mpg:
  • Step 1: Reciprocal: 1 / 30 ≈ 0.03333
  • Step 2: Multiply by 100: 0.03333 * 100 ≈ 3.333
  • Step 3: Adjust units: 3.333 * 2.35215 ≈ 7.84 liters per 100 km
• Convert 35 mpg:
  • Step 1: Reciprocal: 1 / 35 ≈ 0.02857
  • Step 2: Multiply by 100: 0.02857 * 100 ≈ 2.857
  • Step 3: Adjust units: 2.857 * 2.35215 ≈ 6.72 liters per 100 km
