What fraction of the speed of light (c) is 1 m/s?
1 m/s is 1 / 299,792,458 of c in vacuum (about 3.34e-9 c, using the exact SI definition of c in m/s).
Detailed answer
The speed of light c in vacuum is defined as exactly 299,792,458 m/s. Any speed in m/s divided by that constant gives the fraction of c. Relativistic corrections matter only at very large fractions of c; everyday speeds are tiny in these terms.
Relationship context
Astrophysics and particle physics use fractions of c; lab speeds in m/s are easier to grasp when expressed as multiples of this small fraction.
