# How do you convert 16 weeks to seconds?

Sep 4, 2015

You use a series of conversion factors.

#### Explanation:

Every time you need to convert from one unit to another, you need to focus on finding the appropriate series of conversion factors that can be used to convert between the two units.

In your case, you will need to write conversion factors to take you from weeks to days, from days to hours, from hours to minutes, and finally, from minuted to seconds.

This is how your conversion will look like

16color(red)(cancel(color(black)("weeks"))) * (7color(red)(cancel(color(black)("days"))))/(1color(red)(cancel(color(black)("week")))) * (24color(red)(cancel(color(black)("hours"))))/(1color(red)(cancel(color(black)("day")))) * (60color(red)(cancel(color(black)("minutes"))))/(1color(red)(cancel(color(black)("hour")))) * "60 seconds"/(1color(red)(cancel(color(black)("minute")))) = "9,676,800 seconds"

If you want, you can round this off to two sig figs

$\text{16 weeks" = "9,700,000 seconds}$
