That’s faster than a cheetah sprints (100 km/h) but slower than a skydiver in freefall (200 km/h).
Only the U.S., UK, and Liberia stick with mph. (Yes, the UK drives on the left but still measures speed in miles—go figure.)
Imagine cruising down a German autobahn at that clip—just don’t expect to see that limit everywhere.
For 150 km/h: 150 × 0.62 = 93.21 mph. No calculator? Remember that 100 km/h is roughly 62 mph—that’s close enough for most speed checks.
Drive from Basel, Switzerland, into nearby Mulhouse, France, and you’ll feel that drop from 130 km/h to 90 km/h (56 mph) fast.
France went metric early, while the U.S. kept the old British mile-based system. (Blame colonial history, not logic.)
Federal law requires mph on U.S. roads, even in 2026. Cross into Canada, though, and you’ll see those familiar km/h signs.
That’s one adrenaline-packed comparison. Just don’t try racing either of them.
Useful for those sudden speed-limit drops when crossing from Belgium (120 km/h) into the UK (70 mph).
Check your dashboard settings. If not, your GPS app can usually display the unit you prefer.
At 150 km/h, you’re nudging past that suggestion. (Officially, there’s no universal limit, but good luck explaining that to a cop.)
Don’t panic if your rental’s dashboard looks unfamiliar. That 150 km/h mark? It’s just 93 mph.
That’s roughly the speed a skydiver hits before pulling the chute. (Please don’t test this on the highway.)
Drive from France (130 km/h) into Switzerland (120 km/h)? Suddenly your 150 km/h feels way too fast. Always check local signs.
Or memorize these key conversions: 100 km/h ≈ 62 mph, 120 km/h ≈ 75 mph, 150 km/h ≈ 93 mph. Close enough for most drivers.
Set it once, and you’ll never squint at a mismatched speedometer again. Honestly, this is the easiest fix for the whole problem.
