How do you convert km/h to mph?
Multiply the km/h value by 0.6214. In your head, take six tenths: 130 km/h gives 78 mph against 80.8 in reality, a 3 % gap that is plenty for reading a road sign.
km/h = mph × 1.609

Frequently asked questions
What is 130 km/h in mph?
130 km/h equals 80.78 mph. That is the French motorway limit in dry weather, noticeably higher than the British 70 mph, which is 113 km/h.
How do I convert in my head without a calculator?
Subtract a third, then add a little back. For 90 km/h: 90 − 30 = 60, against an exact 55.9 mph. Simpler still, multiply by 0.6: 90 × 0.6 = 54, within 3.5 % of the real figure.
Why does my speedometer show both scales?
Manufacturers sell the same model on both sides of the Atlantic. The main scale matches the sales market, the second lets you drive abroad without misreading your speed.
Can my speedometer read higher than my actual speed?
Yes, and the rules require it. UNECE Regulation 39, applied across the European Union, forbids a speedometer from reading below true speed and allows it to read up to 110% of that speed plus 4 km/h. At a true 130 km/h the dial may legally show 147 km/h, which is 91 mph instead of 80.8.
How does a country switch from mph to km/h?
Ireland did it on 20 January 2005, and it redefined its limits rather than converting them. The 30 mph urban limit, 48.3 km/h, became 50 km/h, and the 70 mph motorway limit, 112.7 km/h, became 120 km/h. Every sign nudged the limit upward on the way.
