KM to Miles

Direct Answer Summary

To convert kilometers to miles, multiply the kilometer distance by 0.621371 (or divide by 1.609344). For example, 100 kilometers equals exactly 62.14 miles, and 5 kilometers equals 3.11 miles. For fast mental estimates on the highway, multiply the kilometer reading by six and drop the last digit (e.g., 50 km × 6 ≈ 30 miles).

The Inverse Relationship

L/100km vs Miles Per Gallon

Because MPG measures distance-per-volume and L/100km measures consumption-over-distance, the formula is inverse: L/100km = 235.215 ÷ US MPG. A smaller L/100km number means better fuel efficiency.

US vs UK Gallons

3.785 L vs 4.546 L Gallons

An Imperial (UK) gallon is 20% larger than a US liquid gallon. Consequently, a car rated at 30 US MPG achieves 36 Imperial UK MPG, though engine efficiency is identical.

Trip Cost Estimation

Fuel Needed × Local Gas Price

To plan your fuel budget: divide route distance by vehicle MPG to get gallons needed, then multiply by local pump price. Aerodynamic highway driving can improve economy by 15–25%.
