Show, using dimensional analysis, how many days there are in 99 weeks.


Expert Answer

Step 1

Conversion factor is a formula which defines the relation between one set of units of a particular quantity with the other sets of units.


For the relationship between days and weeks, the conversion factor used is ‘there are 7 days in one week’.

Step 2

The conversion factor for day and week units is,

1 week = 7 days


Hence, 99 weeks = 7 × 99 days
