A significant figure is the first digit in a number that isn't zero. You round to this.

Step-by-step explanation:

E. g. 1959302 to 1 Sig Fig = 2000000

You round to the first figure that isn't zero, which is one

E. g 0.000001373 to 1 Sig Fig = 0.000001 because that 1 is the first digit that isn't zero
