There is no fixed conversion from miles to hours – it depends on speed. At 60 mph each mile takes one minute; at 30 mph, two minutes; walking at 3 mph, 20 minutes.

Tips

  • Use your own measured figures – fuel economy, speed and prices vary a lot with driving style, traffic, load and season.
  • Pick the unit in each field’s menu (miles or kilometres, mpg or L/100 km); the calculator converts everything for you.
  • Fill up to the brim twice and divide the distance by the fuel added to measure real fuel economy.
  • For vehicle modifications, treat results as a starting point and confirm with the parts maker or a professional mechanic.

Common mistakes to avoid

  • Mixing US and imperial (UK) gallons – a UK gallon is about 20% bigger.
  • Using the advertised fuel economy instead of real-world figures.
  • Forgetting tolls, parking and wear and tear when comparing driving with public transport.

Inputs explained

Field What to enter
Distance Units: mi, km, m, nmi
Speed Units: mph, km/h, m/s, knots

What each result means

  • Time = [Distance]÷[Speed]
  • Time (h min) = [Time]÷3600
  • Minutes per mile = 1609.344÷[Speed]÷60

Formula

Time = distance ÷ speedDistance = speed × time; speed = distance ÷ time

Worked example

Inputs — Distance: 120 mi; Speed: 60 mph.
Results — Time = 2 h; Time (h min) = 2 h 0 min; Minutes per mile = 1.
