Suppose the acceleration due to gravity at a place is 10 m/s2.
Find its value in cm/(minute)2.
1 meter of length contains 100 centimeters i.e. 1m = 100 cm
So 10 meters should contain 10 × 100 cm
10 m = 1000 cm = 103 cm …(i)
1 minute contains 60 seconds so 1 second is 
of a minute
1 minute = 60 seconds 
1 second = 
minute
(1 second)2 = 
minute2 = 
minute2
10 m/s2 =
