What is a hectometer?

A hectometer is an SI unit of length equal to 100 metres, used for measuring distances in mapping, land measurement, and civil engineering.

What is a megaparsec and where is it used?

A megaparsec is a unit of length equal to one million parsecs, commonly used in astronomy and cosmology to express distances between galaxies and large-scale cosmic structures.

Why are conversions from hectometers to megaparsecs so small?

Because a megaparsec is about 10^21 times larger than a hectometer, resulting in extremely small values when converting from the smaller unit to the larger one.
