## Conversion formula

The conversion factor from minutes to seconds is 60, which means that 1 minute is equal to 60 seconds:

1 min = 60 s

To convert 4.5 minutes into seconds we have to multiply 4.5 by the conversion factor in order to get the time amount from minutes to seconds. We can also form a simple proportion to calculate the result:

1 min → 60 s

4.5 min → T(s)

Solve the above proportion to obtain the time T in seconds:

T(s) = 4.5 min × 60 s

T(s) = 270 s

The final result is:

4.5 min → 270 s

We conclude that 4.5 minutes is equivalent to 270 seconds:

4.5 minutes = 270 seconds

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 second is equal to 0.0037037037037037 × 4.5 minutes.

Another way is saying that 4.5 minutes is equal to 1 ÷ 0.0037037037037037 seconds.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that four point five minutes is approximately two hundred seventy seconds:

4.5 min ≅ 270 s

An alternative is also that one second is approximately zero point zero zero four times four point five minutes.
