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 0.4 miles per hour into knots we have to multiply 0.4 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
0.4 mph → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 0.4 mph × 0.8689762419014 kt
V(kt) = 0.34759049676056 kt
The final result is:
0.4 mph → 0.34759049676056 kt
We conclude that 0.4 miles per hour is equivalent to 0.34759049676056 knots:
0.4 miles per hour = 0.34759049676056 knots
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 2.8769486200564 × 0.4 miles per hour.
Another way is saying that 0.4 miles per hour is equal to 1 ÷ 2.8769486200564 knots.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that zero point four miles per hour is approximately zero point three four eight knots:
0.4 mph ≅ 0.348 kt
An alternative is also that one knot is approximately two point eight seven seven times zero point four miles per hour.
