2. Divide the number of seconds by 60 to convert seconds to minutes. Every 60 seconds a full minute has passed. Dividing a number tells you how many times one number fits in the other.
For example, 90 seconds equals 1.5 minutes (90 / 60). This means that there is 1 minute plus an extra half of a minute (.5 of a minute) in 90 seconds. To convert this back to seconds, simply multiply the decimal by 60. Answer: There is 1 minute and 30 (.5 x 60) seconds in 90 seconds.
