alt Hacker NewsCan someone please please PLEASE tell SpaceX PR/Streaming team that the speed (per SI system) is measured in meters per second, not kilometers per hour? The speed of sound is approx 300 m/s, orbital velocity is approx 8,0000 m/s (depending on altitude), free fall acceleration on Earth is 9.81m/s, 1.63m/s on the Moon, the speed of light is apporx 300,000,000 m/s, people learn these numbers in middle school. It's not 1000 km/h, or 28,000 km/h, it just looks so weird.
Edit: ok, acceleration is meters per second per second, but my point stands.

I understand the appeal of using the same combinations everywhere, but I thought the great thing about the metric system was that it was easy to convert. So 8000 m/s is 8 km/s.

They are likely appealing to the common population who mostly think of speed in mi/h or km/h due to car speeds
