Knots to MPH Converter

Convert between knots and miles per hour

What is This Tool?

Speed converters translate between common velocity units including miles per hour (mph), kilometers per hour (km/h), meters per second (m/s), knots (nautical miles per hour), and Mach numbers. They are vital for driving, aviation, maritime, and scientific applications.

Formula
target = value x (source unit in m/s) / (target unit in m/s) Base unit: meters per second (m/s) 1 km/h = 0.2778 m/s, 1 mph = 0.4470 m/s, 1 knot = 0.5144 m/s
Worked Examples

1. MPH to KPH

Given: 65 mph

1 mph = 1.60934 km/h

65 x 1.60934 = 104.607 km/h

Result: 104.607 km/h

2. Knots to MPH

Given: 20 knots

1 knot = 1.15078 mph

20 x 1.15078 = 23.016 mph

Result: 23.016 mph
