Conversion Formula
The formula for converting mph to km/h multiplies the mph value by 1.60934, which is the number of kilometers in one mile. This works because the metric system measures distances in kilometers, and the imperial system in miles. For example, 90 mph equals 90 × 1.60934, resulting in 144.8406 km/h.
Conversion Example
- Convert 60 mph to km/h:
- Step 1: Write the formula: km/h = mph × 1.60934
- Step 2: Multiply 60 by 1.60934: 60 × 1.60934 = 96.5604
- Result: 60 mph equals 96.5604 km/h
- Convert 45 mph to km/h:
- Step 1: Multiply 45 by 1.60934
- Step 2: 45 × 1.60934 = 72.4203
- Result: 45 mph equals 72.4203 km/h
- Convert 100 mph to km/h:
- Step 1: 100 × 1.60934
- Step 2: 100 × 1.60934 = 160.934
- Result: 100 mph equals 160.934 km/h
