What does one picometer represent?

A picometer is an SI unit of length equal to 10⁻¹² metres, used to describe very small distances such as atomic and molecular bond lengths.

What is a megaparsec used for?

A megaparsec equals one million parsecs and is commonly used to measure vast distances between galaxies and cosmological structures.

Why do converted values between pm and Mpc involve scientific notation?

Because picometers and megaparsecs differ by an immense scale, converted values become extremely small or large, requiring scientific notation for clarity.
