## Conversion formula How to convert 9 minutes to seconds?

We know (by definition) that: $1\mathrm{min}=60\mathrm{sec}$

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

$1 ⁢ min 9 ⁢ min = 60 ⁢ sec x ⁢ sec$

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

$x\mathrm{sec}=\frac{9\mathrm{min}}{1\mathrm{min}}*60\mathrm{sec}\to x\mathrm{sec}=540\mathrm{sec}$

Conclusion: $9 ⁢ min = 540 ⁢ sec$
