Convert the following into basic units:
a. `28.7 p m`
b. `15.15 p m`
c. `25365 mg`

Text Solution

Verified by Experts

a. `28.7 "pm"=28.7 "pm"xx(10^(-12)m)/(1 "pm")=2.87xx10^(-11) m`
b. `15.15 mus=15.15 musxx(10^(-6)s)/(1 mus)=1.515xx10^(-5)s`
c. `24=5365 mg=25365 mgxx(1g)/(1000 mg)xx(1 kg)/(1000 g)`
`=2.5365xx10^(-2) kg`
