Formula and precision

Fuel consumption units often have an inverse relationship (e.g., L/100km to MPG).
Yes. Conversions run locally in your browser using verified ratios and display up to 8 decimals. Some categories like temperature and fuel use specialized formulas.
  • Use smaller units for higher precision, then convert back if needed.
  • Temperature and fuel categories can’t be reduced to one constant multiplier.
  • Symbols vary by region (US/UK gallons, metric vs. imperial abbreviations).
  • For engineering work, validate with a second reference and keep unit symbols.

Quick examples

Example: 5 L/100km = 2.12571854 gal (US)/100mi.

Common mistakes and definitions

Fuel efficiency units can be inverse (MPG vs L/100km). A higher MPG corresponds to a lower L/100km, so always verify direction and gallon standard.
  • Reversing the relationship between MPG and L/100km (inverse units).
  • Using the wrong gallon definition (US vs UK/imperial).
  • Comparing values converted with different distance standards without noticing.
