How do I calculate speed

1 knot equals 0.514 metres per second.
2 knots equals 1,028 metres per second.

10 knots equals 0.514 * 10 = 5.14 metres per second

15 knots equals 7.71 metres per second

You don't want to measure the speed by cutting the 3:15 rule in half, nor in 4 pieces, you need the 3 minutes and 15 seconds because SH5 uses intervals of 50 metres, you can't measure lower than that, plot your marks very carefully at fully zoomed level, be accurate.

1: Plot a mark on the ship
2: Start stopwatch
3: Wait 3:15
4: Be ready to plot the ship again exactly at 3:15 at the exact same place on the ship
5: Measure the length between the two points, remove the last 2 digits and there is your speed (or simply put a comma separator before the last two digits)
