Homework Help!! Nautical miles

Recommended Posts

I need to convert 35 Nautical miles ( hour) to Statute miles (hour). and visa versa.

I know 6067 feet =1 knot, and to get from knots to miles I have to go, 1 knot over 1hour times 6067 feet over 1knot times 1mile over 5280 feet (( next step??)) and I need to get the time in there somewhere so would it be 1 hour = 6 min or 1hour = 3600 seconds?

Or am I missing the whole thing completely?? it is a bit confusing over the post. So here
is the link to the homework it is on page 7 of 9.

I just started Oceanography and it is a bit over my head at this point.

Thanks so much.:)

40.277265 or so, depending on your rounding requirements . . . 40.3 is actually a bit closer to reality.

The close enough for most work answer is going to be to multiply knots by 1.15 for 40.25.

I just need to show how you got that answer!



One of those things I remember from the Navy in California.

To convert nautical miles to statute miles multiply your nautical miles by 1.15

To convert statute miles into nautical miles multiply the statute miles by .87 (I think).

Click here to cheat.



I would discourage people from learning something by using a cheat. He may not have a working computer on a ship when he needs to do a quick conversion. There's an easy method to learn it without using a computer.

I know...imagine that...actually learning something instead of Googling it. *GASP*

Knowledge of both the question and the answer is mutually exclusive.

Tuna planet has the answer to the "ultimate question"...... forty- two:D

Now what was the question?:ph34r:

The ultimate question of the universe is . . . . . .What is six times seven?

Hitchhiker's Guide to the GAlaxy



Err... NO!!! The ultimate answer WAS 42. The ultimate question was "What is seven times FIVE? Thus proving that the universe itself is fundamentally flawed.:ph34r::ph34r::S

You don't really need to worry about time from the math perspective. You start with miles/hour and end with knots/hour.

35mi .... 5280ft .. knot
----- X ------ X ------ = 30.31 knots/hour
hr ......... mi ..... 6097ft

Note that miles and feet are both in the numerator and the denominator and thus cancel out. It's often easy to line up the conversion rates like this so that the numerator is cancelled out by the denominator of the next fraction.

Effectively all you're doing is multiplying the speed by the difference between knots and miles, which is .866 going from mph to knots/hr, or 1.154 the other way.

"You start with miles/hour and end with knots/hour."

Are knots different in the States?
Over here we have nautical miles, as a measure of distance, Knots are a measure of speed.

Therefore if you are looking at knots/hour, that would actually be a measure of acceleration.:S

Anyways there are loads of wee conversion programmes out there to download, http://www.haywardindustrial.com/html/converter/converter.asp for example, stick one on yer desktop.B|

My wee convertor says 1 nautical mile is 6076.131ft
near as dammit to your 6080.
In metric I believe its 1852m.

fromhttp://www.gwydir.demon.co.uk/jo/units/sea.htm
"Nautical miles measure distance. 1 nautical mile is the angular distance of 1 minute of arc on the earth's surface. As these differ slightly (6108' at pole c.f. 6046' at equator) 6080 was adopted (this being it's approximate value in the English Channel). The International nautical mile is 1852 metres, so is very slightly different from the UK nautical mile.


1 UK nautical mile = 1.00064 international nautical miles
Now the International nautical mile is used throughout the UK, except in the Statutory Instrument 1995 No. 1804 which defines it as 1853 metres! If you want an irrelevant fact, one minute of arc on Mars is close to a kilometre (.987 km to be more accurate). Perhaps the French who defined the kilometre were really Martians! "

Hence the phrase "cheese eating surrender aliens"
I hope that clears everything up.B|

"I don't think anyone uses knots to mean distance anymore, but it is a correct usage."

Well I'll stand corrected, I've only ever experienced knots as speed, which is why I asked.
Cheers Dave.:)

We did some of the time in the Navy.

Also, nautical miles are used for open water (oceans, seas, etc...). Statute miles are used for inland waters (lakes, rivers, etc...).
