- dclowd9901 7y agoDoes knots even make sense outside of the context of being located on a sphere?
- asib 7y agoAccording to https://en.wikipedia.org/wiki/Nautical_mile https://en.wikipedia.org/wiki/Nautical_mile, nautical mile used to be defined as 1/60 of a degree of latitude, but is now defined as exactly 1852 metres. So feasible to use even in space, although unusual.
- coldtea 7y agoThey are not particularly tied to spheres -- it's just nautical miles per hour, no? As such it can be a totally abstract unit, regardless of the origin (the same way feet can be used to measure something that doesn't involve a walk). Aviation also uses them (though they still fly above a sphere).

- Gibbon1 7y agoWe could talk radians per second.
- Bjartr 7y agoThe solar system is moving at about 143 miles per second.
