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 159.5 miles per hour into knots we have to multiply 159.5 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

159.5 mph → V_(kt)

Solve the above proportion to obtain the velocity V in knots:

V_(kt) = 159.5 mph × 0.8689762419014 kt

V_(kt) = 138.60171058327 kt

The final result is:

159.5 mph → 138.60171058327 kt

We conclude that 159.5 miles per hour is equivalent to 138.60171058327 knots:
