Common questions
What is 70 mph on European speed limit signs?
70 mph is about 113 km/h. Many European highways allow 130 km/h (roughly 81 mph), but limits vary by country and road type — always follow local signage.
Does my car speedometer show both units?
Some US cars show a secondary km/h scale inside the mph dial. Rental cars abroad usually default to km/h. GPS speed readouts often follow app settings, not the car dial.
How do I avoid speeding tickets when switching between mph and km/h?
Convert the posted limit before you drive. A common mistake is treating “100” as mph when the sign means 100 km/h (about 62 mph). Set your GPS to display the local unit.
Are wind speeds in weather reports converted the same way?
Yes — the same factor applies because both use distance per hour. US hurricanes may quote mph; international forecasts often use km/h or knots (1 knot ≈ 1.852 km/h).
