Value

A KPH to Knots Speed Converter is an essential tool for converting between kilometers per hour (kph) and knots (kt), particularly useful in aviation, marine navigation, and meteorology where different speed units are standard.

Understanding KPH and Knots

1. Kilometers per Hour (kph)

• The metric system unit used worldwide for road vehicles and weather reports
• Measures distance in kilometers traveled in one hour

2. Knots (kt)

• standard unit in aviation, maritime, and meteorological applications
• 1 knot = 1 nautical mile per hour (1.852 kph exactly)
• Based on the nautical mile (1,852 meters)

Conversion Formulas

KPH to Knots

$$\text{Knots}=\frac{\text{KPH}}{1.852}$$

or equivalently:

$$\text{Knots}=\text{KPH}\times 0.539957$$

Knots to KPH

$$\text{KPH}=\text{Knots}\times 1.852$$

Practical Conversion Examples

• Example 1: Convert 100 kph to knots

$$\frac{100}{1.852}=53.9957\text{ kt}$$

or

$$100\times 0.539957=53.9957\text{ kt}$$

• Example 2: Convert 30 knots to kph

$$30\times 1.852=55.56\text{ kph}$$
