How many seconds are there in 2 days ?

Explanation

Here, we know 1 day =24 hours (h)
`or ("1 day")/("24h")=1=(24h)/("1 day")`
then 1h=60min or `(1h)/("60 min")=1=("60min")/(1h)`
For converting 2 days to seconds
The unit factors can be multiplied in series in one step only as follows:
`"2 day" xx (24h)/("1 day") xx ("60min")/(1h) xx (60s)/("1min")`
`=2 xx 24 xx 60 xx 60s=172800s`
