## 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.

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

## Conversion in the opposite direction

The inverse of the conversion factor is that **1 second is equal to 0.00185185185185185 times 9 minutes**.

It can also be expressed as: 9 minutes is equal to $\frac{1}{\mathrm{0.00185185185185185}}$ seconds.
