Summarize why a scientist measuring the diameter of an atom or the distance to the moon would use scientific notation

A scientist using ordinary decimal notation would have to write the diameter of, say, a helium atom as 0.000 000 000 062 m and the distance to the moon as 340 000 000 m.

It is inconvenient, tedious, and cumbersome to write all those zeroes.

It is much easier to write these numbers in scientific notation as 6.2 * 10⁻¹¹ m and 3.4 * 10⁸ m.
