Convert the following into basic units:
(i) 28.7 pm
(ii) 15.15 pm
(iii) 25365 mg

Explanation

(i) `28.7 pm = 28.7 "pm" xx (10^(-12) m)/(1 "pm") = 2.87 xx 10^(-11) m`
(ii) `15.15 mu s = 15.15 mus xx (10^(-6) s)/(1 mu s) = 1.515 xx 10^(-5) s`
(iii) 25365 mg = `25365 xx (1 g)/(1000 mg) xx (1 kg)/(1000 g) = 2.5365 xx 10^(-2) kg`
