step 1: determine your starting point.
step 2: determine your ending point.
step 3: locate the decimal point.
step 4: count the jumps you moved to reach your ending point.
step 5: move the decimal to the same number of jumps in the same direction.
sample q: 4 km = m
step 1: starting point is km
step 2: ending point is m
step 3: decimal point is right after 4
step 4: moved 3 decimal places to the right
step 5: 4 km = 4000 m
