Nautical mile calculator

Anyone use one of these to get distances easily. Was thinking of ordering one to punch in numbers when WO calls out feet instead of yards or to help when SO reports yards to get miles the contact is at.

I created a spread sheet in Excel that shows yards to miles conversion up to 80,000 yards (for radar) and also a feet/meters table for ship drafts and heights. Although, if you get the latest recognition manual mod, the numbers reflect metric or imperial, based on your setup. I like using the poster, because it gives a better 3D view of the models, which shows the values in metric.

Would you mind sharing it, the spreadsheet, i would love to use it if thats ok with you.

Not 100% accurate, but a simple in-your-head calculator:

1nm = 2000 yards = 6000 feet

This is exact if you need to know

1nm = 1.15mph = 2024yards = 6072 feet

Black1, I sent you the spreadsheet a few minutes ago. Hope it helps.

You can also download the Microsoft Calculator Plus, which lets you convert anything out there!

No, that's not exact, or right. The correct conversion is 1.150779, making the nautical mile 2025.372 yards, or 6076.1155 feet. The nautical mile went through several changes over the years, but the one used in WW2 was set at exactly 1852 meters by the 1929 International Extraordinary Hydrographic Conference.

Of course we don't usually trust Wiki, so I would also refer you to a library to find a copy of the American Practical Navigator, which is the definitive source for all good sailors.

Yeah, I'm using 2025.37yds for the international nautical mile. I don't know what the game's calling a NM, but this seems to work fine for me.

Also using 34yds/minute for one knot. I think it's actually 33.8 with a few more decimal places, but we're not heading to Jupiter so the calculations aren't thrown off too much.

As far as I'm concerned, the bottom line: God bless the nomograph and the distance-speed-time triangle
