Question

A red blood cell has a mass of about 0.000000000027 g. Convert this mass to an appropriate SI prefix and unit, so the number portion does not need a decimal place (i.e. an integer number). Your answer must include the number and the appropriate unit symbol.
isn't it 27picograms?

Answer 1

Teragram(T) to the power of $10$ is $10^{12}$ While Picogram(P) to the power of $10$ is $10^{-12}$

Converting $2.7\times10^{-11}$ to appropriate SI units will hence be;

$2.7\times 10^{-11} \times10^{12}$ $=27$ Teragrams(T)
