a knot is 1 nautical mile per hour so the conversion is exactly the same as your speed question

Hold your breath...... a nautical mile is 6,076.11549 feet, or 2025.3717966 yards or 1,852 metres. Much easier to say one minute of latitude.

[BrendanS]

one minute of latitude, at the equator

otherwise it all rapidly goes pear shaped, so to speak

It's all pretty basic stuff. Posted at same time as you, so didn't see the possible amusement factor, but he knows the answers anyway

Knot derives from chucking a wooden sea anchor overboard with a line attached, then timing the number of equidistant knots tied in the line that went overboard

One minute of latitude everywhere. It only goes "pear shaped" on a Mercator chart. A nautical mile is exactly the same the world over, or it was when I was in the Navy.

1' of arc varies from 1842.9m at the equator to 1861.7m at the poles with a mean value of 1852.3m at Latitude 45 deg.

The International nautical mile is actually 1852m, not to be confused with a sea mile.

A knot is 1 International nautical mile (1852m) per hour.

"The International nautical mile is actually 1852m, not to be confused with a sea mile."

"nautical" & "sea" distinctly related yes ? so it should be safe to assume nautical mile = sea mile yes?

Cos of the knots on the original string and wood speed measuring devices.

Around here 1.2mph = 1 knot approx.
