What is a petagram (Pg)?

A petagram is an SI unit of mass equal to 10^15 grams or one billion metric tonnes, used mainly in geosciences and climate science.

What is a centigram (cg)?

A centigram is a metric unit of mass equal to one hundredth of a gram (0.01 g), often used to measure small masses in labs or pharmaceuticals.

Why convert petagrams to centigrams?

Converting petagrams to centigrams helps bridge the gap between very large mass measurements and very small, precise masses used in laboratory and pharmaceutical contexts.
