Conversion formula
The conversion factor from miles per hour to knots is 0.8689762419014, which means that 1 mile per hour is equal to 0.8689762419014 knots:
1 mph = 0.8689762419014 kt
To convert 4.2 miles per hour into knots we have to multiply 4.2 by the conversion factor in order to get the velocity amount from miles per hour to knots. We can also form a simple proportion to calculate the result:
1 mph → 0.8689762419014 kt
4.2 mph → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 4.2 mph × 0.8689762419014 kt
V(kt) = 3.6497002159859 kt
The final result is:
4.2 mph → 3.6497002159859 kt
We conclude that 4.2 miles per hour is equivalent to 3.6497002159859 knots:
4.2 miles per hour = 3.6497002159859 knots
