An adult human is made up of around 7,000,000,000,000,000,000,000,000,000 atoms!

An adult human is made up of around 7,000,000,000,000,000,000,000,000,000 atoms!

The number of atoms in one person is almost too big to write out. But fortunately there's a shorthand system, called scientific notation that we use instead for writing really BIG or really SMALL numbers.

Since huge numbers are generally just estimates anyway, we just use the first few numbers, followed by a code that tells you how many zeros would follow if you wrote it all out.

Hydrogen, oxygen and carbon make up about 99% of the average human. The other 1%, is made up of trace elements. Then, let's assume an average adult weighs 70 kilograms.

Keep in mind that the following numbers are based on the number of atoms, not percent of body weight (by weight we are mostly oxygen). A 70 kg body would have approximately 7*1027 atoms. That is, 7 followed by 27 zeros:

7,000,000,000,000,000,000,000,000,000

And yet we are just a tiny part of the entire universe.
