What i think is foolish ,is that the speed is measured in knots(=nm/hr)
while the distance tool in the map measure in Km
So when you want to calculate the nm you have to make an extra calculation.
If i am wrong i am sorry and i would appreciate if someone know how to change the units in the distance tool in the map to nm
Thanks!!! |

i dont think you can, because they are two distinct measurements.
km is a distance
knots is a speed |

I agree with you, Miker. The Devs apparently are landlubbers at heart
km x .54 = nautical miles |

And 1 knot = 1.852km per hour
I did put together a rather basic Excel spreadsheet so I could calculate distances travelled by targets over time. It took a calculation out of my game and made life a bit easier.

Using 1 Knot = 2 Km/hr introduces only a 5% error and is accurate enough for almost all purposes.

I meant to change the distance tool units to nm or speed unit to km/h
irish1958 by using this technique of 1nm =about 2km is good ,this is what i am doing but for large distances you have to be accurate and then the distance tool might confuse you
Thanks |

There is a neat mod/feature in GW (also available as a standalone mod, I suspect) that gives you a couple of pull-down charts you can drag over your nav map screen that give you the distance (in km) that a ship will travel over various time periods (one sheet lists time in hour increments, the other sheet in smaller increments - maybe 10-15 minute chunks) at various speeds - a very handy way of doing the conversions without having to compute anything.
Since the TDC range dials are marked in meters and not nm, having the nav map tool measure off meters actually is a good idea - otherwise we'd just have to do conversions the other way to set up our shots. |
