Some common speeds:

jog 5 mph = 8 * 10^-9 c

Car 55 mph = 8 * 10^-8 c

Jet aircraft 550 mph = 8 * 10^-7 c

space shuttle 7.7 km/s = 2.6 * 10^-5 c

Speed of voyager 1, 17 km/s = 5.7 * 10^-5 c

speed of the earth in its orbit 30 km/s = 10^-4 c

speed of the sun in its orbit 225 km/s = 7.5 * 10^-4 c

Speed of the Milky Way galaxy 600 km/s = 2 * 10^-3 c

speed of an electron in a color television 10^8 m/s = 0.3 c

speed of an electron in the Stanford Linear Accelerator 3 * 10^8 m/s = 0.9999999995 c
