Not sure if this is what you are looking for but try

Site Link

click on "Get directions"

Enter 'from' and 'To' been the 2 locations you want

Not 'as the crow flies' but actual distance

Calculating the shortest distance between two points on the earth's surface is calculating the Great Circle Route.

In my early days in Air Traffic Control this was a traditional job to give the newbies (me) and we had to work it out on paper, no calculators.

It's easier these days provided you have the lat and long, which you can get from Google Earth.

Here's how:

Have fun.

Great circle calculation bit over the top for sort distances i.e. no appreciable difference to a ruler on a map for the distance that a 4WD would do. And it ties the brain up in knots.

OP did not say what the application was for. i keep a set of [marine navigation] callipers in the car and use that against the map's scale; I use GPS GOTO feature for measurement line-of-sight [or as-the-crow-flies]; I use Google Earth and mapping software to measure road distances.

Heap of stuff on the net, as other posters have mentioned

Dividers on a chart - but use the scale on the side of the chart for your dividers width setting as Lat stays true but the scale on top and bottom 9LONGITUDE) gets closer the larger the longitude south of the equator...so is not accurate for distance measurements!

You'll get answers in nautical miles, (1 degree is 60 Nm and One Minute is 1Nm) but you can convert them to kilometers with a calculator, abacus or slide rule.

That said, crows tend to fly overland, you might wanna go as the albatross flys for over water distances!. ;o)
