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 = 60 min or `(1h)/("60 min")=1=("60 min")/(1h)`
For converting 2 days to seconds.
The unit factors can be multiplied in series in one step only as follows :
`"2day"xx(24h)/("1 day")xx("60 min")/("1 h")xx(60s)/("1 min")`
`=2xx24xx60xx60s=1172800s`
