1. Speed and Distance Coversions

10 knots                  18.5 km / hr          10 * 1.852 = 18.52 ~ 18.5

18.5 km                   10 NM                 18.5 / 1.852 = 9.9892 ~10

5.5 NM                    10.2 km               5.5 * 1.852 = 10.186 ~ 10.2

7 NM/hr                   13.0 km/hr            7 * 1.852 = 12.964 ~ 13.0

2 kts                     3.7 km / hr           2 * 1.852 = 3.702 ~ 3.7

30 km / hr                16.2 Knots            30 / 1.852 = 16.198 ~ 16.2 kts

3 NM                      5556 Metres           3 * 1.852 = 5.556 km* 1000 = 5556 Meters

305 metres                1000.6 feet           305 / 0.3048 = 1000.656 ~ 1000.6

20 knots                  10.3 Metres / sec     20 * 1852 / 3600 = 10.288 ~ 10.3

500 ft / min              9.1 km / hr           500 * 0.3048 * 60 / 1000 = 9.144 ~ 9.1

2. Time / Distance / Speed

10 knots              36 minutes                6.0 NM            10 / 60 * 36 = 5.999 ~ 6.0

10 km / hr            33 minutes                 5.5 km           5.5 / 10 * 60 = 33

7 NM/hr               40 minutes                 8.6 km           8.6 / (7 * 1.852) * 60 = 39.8 ~ 40

24 km / hr            35 minutes                 14 km            14 / 35 * 60 = 24

30 km / hr            40 minutes                20.0 km           30 / 60 * 40 = 20

18 knots              50 minutes                15.0 NM           18 / 60 * 50 = 15

20 knots              75 minutes                 25 NM            25 / 75 * 60 = 20

24 km / hr            25 minutes                 10 km            10 / 24 *60 = 25

9 knots              43 minutes                 12 km            12 / 43 * 60 / 1.852 = 9.04 ~ 9.0
