See Makman64's image in his first post, like he said.
Just look at the S-mark (for speed obviously). If you look at the outer rings in Makman64's image in the first message, you see for example 100 is aligned with 100. That means 100 meters in 100 seconds, or 1 meter per second. Then you look down to the S, and see 1.94 opposite from it. That means 1.94 knots.
How was that derived? Pure mathematical magic! Makman64 no doubt used different numbers in the formula (because of a different max zoom level) but it is basically the same form as in the link below. Here is the post how I calculated the S mark for one of the first OLC-Gui versions. Just to give you an idea how.
