The metre is defined as the distance travelled by light in `1/(299,792,458)` second. Why didn't people choose some easier number such as `1/(300,000,000)` second? Why not 1 second?
Suppose you are told that the linear size of everything in the universe has been doubled overnight. Can you test this statement by measuring sizes with a metre stick? Can you test it by using the fact that the speed of light is a universal constant and has not changed? What will happen if all the clocks in the universe also start running at half the speed?
Suggest a way to measure the distance between the sun and the moon.

The defining equations are p = q.d and M = IA;
