What Is a Second?
The second (s) is the SI base unit of time. Since 1967, it has been defined as the duration of 9,192,631,770 periods of the caesium-133 atom's ground-state hyperfine transition. The second is the foundation for all SI time measurements and is also used to define the meter (via the speed of light) and other derived units.
What Is a Minute?
The minute (min) is a unit of time equal to exactly 60 seconds. It is not an SI unit but is accepted for use with the SI system. The minute originates from the Babylonian sexagesimal (base-60) number system, which divided the hour into 60 equal parts over 4,000 years ago.
Seconds to Minutes Formula
The conversion is exact by definition:
minutes = seconds ÷ 60 exact
Since 1 minute = 60 seconds exactly, dividing by 60 always gives the precise result. No rounding of the conversion factor is needed.
Worked Example
Convert 90 seconds to minutes:
- Divide: 90 ÷ 60 = 1.5 minutes (1 minute 30 seconds)

Why 60 Seconds in a Minute?
The number 60 comes from the Babylonian sexagesimal system, inherited from the Sumerians around 2000 BCE. The Babylonians chose base-60 because it has many divisors (1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60), making fractions easy to express. This system was adopted by Greek astronomers, passed to medieval Islamic scholars, and eventually became standard in Western timekeeping. The same base-60 logic gives us 60 minutes in an hour and 360 degrees in a circle.
When You Need This Conversion
- Sports timing: Sprints and swimming are timed in seconds, but longer events report minutes. A 240-second 400 m swim = 4:00 minutes.
- Computing: Timeouts and latencies are specified in seconds or milliseconds. A 300-second timeout = 5-minute session expiry.
- Cooking: Microwave and oven timers use minutes, but recipes sometimes specify seconds for precision tasks. Searing meat for 90 seconds = 1.5 minutes per side.
Frequently Asked Questions
How many seconds are in 5 minutes?
300 seconds (5 × 60). This is a common timer setting and the standard delay for many countdown applications.
Why are there 60 seconds in a minute?
The number 60 comes from the Babylonian base-60 (sexagesimal) number system, inherited from Sumerian mathematics around 2000 BCE. It was chosen because 60 has 12 divisors, making it easy to divide into fractions.
How many seconds are in an hour?
3,600 seconds (60 minutes × 60 seconds). This is why clock faces sometimes show a "3600" at the end of a countdown hour.
How many seconds are in a day?
86,400 seconds (24 × 60 × 60). Unix timestamps count seconds since January 1, 1970, so each day increments by 86,400.
How do I convert minutes and seconds to decimal minutes?
Divide the seconds by 60 and add to the minutes. Example: 3 minutes 45 seconds = 3 + (45 ÷ 60) = 3.75 minutes.
