[hqcyppwu] Angles of space and time

The earth turns 360 degrees every 24 hours, so
15 degrees of arc = 1 hour of time
1 degree of arc = 4 minutes of time
1 minute of arc = 4 seconds of time
1 second of arc = 0.0666... seconds of time.

At the equator
1 degree of arc = 111319 m
1 minute of arc = 1855 m
1 second of arc = 30.9 m
.0323 seconds of arc = 1 m
8.98 * 10^-6 degrees of arc = 1 m
Rotation speed = 463.8 m/s
