Conversion

400 seconds is equivalent to 6.66666666666667 minutes.^[1]

Conversion formula
How to convert 400 seconds to minutes?

We know (by definition) that: $1 \sec \approx 0.016666667 \min$

We can set up a proportion to solve for the number of minutes.

\frac{1 \sec}{400 \sec} \approx \frac{0.016666667 \min}{x \min}

Now, we cross multiply to solve for our unknown $x$ :

x \min \approx \frac{400 \sec}{1 \sec} * 0.016666667 \min \to x \min \approx 6.6666668 \min

Conclusion: $400 \sec \approx 6.6666668 \min$

400 seconds is equivalent to 6.66666666666667 minutes

Conversion in the opposite direction

The inverse of the conversion factor is that 1 minute is equal to 0.15 times 400 seconds.

It can also be expressed as: 400 seconds is equal to $\frac{1}{0.15}$ minutes.

Approximation

An approximate numerical result would be: four hundred seconds is about six point six seven minutes, or alternatively, a minute is about zero times four hundred seconds.

Units involved

This is how the units in this conversion are defined:

Seconds

"The second (symbol s) is the base unit of time in the International System of Units. It is qualitatively defined as the second division of the hour by sixty, the first division by sixty being the minute.[3] SI definition of second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom. Seconds may be measured using a mechanical, electrical or an atomic clock. SI prefixes are combined with the word second to denote subdivisions of the second, e.g., the millisecond (one thousandth of a second), the microsecond (one millionth of a second), and the nanosecond (one billionth of a second). Though SI prefixes may also be used to form multiples of the second such as kilosecond (one thousand seconds), such units are rarely used in practice. The more common larger non-SI units of time are not formed by powers of ten; instead, the second is multiplied by 60 to form a minute, which is multiplied by 60 to form an hour, which is multiplied by 24 to form a day. The second is also the base unit of time in other systems of measurement the centimetre–gram–second, metre–kilogram–second, metre–tonne–second, and foot–pound–second systems of units."

Minutes

"The minute is a unit of time or of angle. As a unit of time, the minute is equal to 1⁄60 (the first sexagesimal fraction) of an hour, or 60 seconds. In the UTC time standard, a minute on rare occasions has 61 seconds, a consequence of leap seconds (there is a provision to insert a negative leap second, which would result in a 59-second minute, but this has never happened in more than 40 years under this system). As a unit of angle, the minute of arc is equal to 1⁄60 of a degree, or 60 seconds (of arc). Although not an SI unit for either time or angle, the minute is accepted for use with SI units for both. The SI symbols for minute or minutes are min for time measurement."
