How to convert seconds to minutes

The minute is exactly 60 seconds. The second is the SI base unit of time, defined by the caesium-133 hyperfine transition.

Worked example — 180 s: 180 × 0.0166667 = 3 min.

About seconds and minutes

Second (s)

1 s = 0.0166667 min

Definition. The SI base unit of time, defined by the caesium-133 hyperfine transition

History and origin

The second was historically one 86400th of a day, but since 1967 it has been defined by the caesium atom, as 9 192 631 770 oscillations of its radiation. This atomic definition made it far more precise than astronomical timekeeping.

Current use

The second is the SI base unit of time, underlying clocks, timers and all scientific measurement.

Minute (min)

1 min = 60 s

Definition. Exactly 60 seconds

History and origin

The minute, exactly 60 seconds, comes from the Babylonian base-60 system passed down through astronomy, the same system that gives 60 minutes to the hour. Its name means a small part.

Current use

Minutes are an everyday unit for timing, scheduling and cooking.

Where people use this

Seconds: timers, physics. Minutes: everyday timing, cooking. 90 seconds is 1.5 minutes.

How we know this is right
The factor is fixed by the standards that define the units, not chosen — so it is exact, not a measurement:
1 min = 60 s, so 1 s = 1 ÷ 60 = 0.0166667 min.

Every value is carried to full double precision; the display is rounded.

Both units are defined in BIPM SI Brochure (2019); the second is defined by the caesium-133 transition.
