Frequently Asked Questions

60 mph equals approximately 96.56 km/h. Common speed conversions: 30 mph = 48.3 km/h, 55 mph = 88.5 km/h, 60 mph = 96.6 km/h, 65 mph = 104.6 km/h, 70 mph = 112.7 km/h, 80 mph = 128.7 km/h, 100 mph = 160.9 km/h.

Multiply by 1.6 for a quick approximation. For example, 50 mph × 1.6 = 80 km/h (exact: 80.47 km/h). Another trick: add 60% of the mph value. So 50 mph + 30 (60% of 50) = 80 km/h.

Common European speed limits in km/h: city/urban areas typically 50 km/h (31 mph), rural roads 80-90 km/h (50-56 mph), expressways 100-110 km/h (62-68 mph), and motorways/highways 120-130 km/h (75-81 mph). Germany's Autobahn has sections with no speed limit but a recommended speed of 130 km/h.
