Hi there Papa G

Have you installed GWX? With this mod there are some speed conversion tables that are extremely useful.

I have also built myself a KM whiz wheel.

These things are worth their weight in gold, and can be used for so much. One of the small capabilites of the reverse side, which is a cricular slide rule, is that you can very quickly cross reference 1000m with 9 minutes to obtain a speed of 3.6knots.

Alternatively you can install any of the nomograph mods, which enable you to do this. A nomograph is a scale that will appear on your navmap and can be used to solve any speed/time/distance calculation assuming you know two of the factors. Run a search to find a nomograph mod. You can also find them linked from Wazoo's basic manual targetting tutorial.

Finally, you can just make sure that you take time measurements in increments of 3min15seconds. In 3min 15secs an object moves 100m for every knot of speed, so a 6knot object travels 600m, or 0.6km. At 9min 45 secs therefore a 6 knot object travels 1.8km. (kilometers is written with a small km; KM means Kriegsmarine).

If you'd taken your reading at 9min 45secs, and it had travelled 1200m, the speed would be 1200/3 per 3min 15 secs= 400m per 3 min 15 secs = 4 knots
