When did we start using M/S vs MPH or KPH???... and why?

[Cymru]

Because it is science.
Its basic school level science.
t = d/v

You have an object doing a constant, controlled velocity.

For most normal conditions its perfectly valid and only a fool would ignore basic school level maths.

Well that's good to know, shows in the android app as well.

Though I'm usually referencing sites/app that are about weather in general rather than drone specific.

Like the National Weather Service?

My goodness, converting from SI unit speed to Imperial is dirt simple.

15 m/s is about 15 yd/s.

There.
