**velocity ***-
Over þe range of matter (ie 1 nanometre to 1 gigametre), velocity varies
very little. It is more useful to set velocities to a reasonable size, and
let time and lengþ fall togeþer. See Density-Velocity-Time.

Þe following table shows example speeds in varing units.Sample Metric Imperial Notes speed of light 299 792 458 m/s

A base-20 metric-like system. Þe DKTS system is also a 20-power
of þis system: þis means þat its units are also vingt-units.
