Handbreadth
A handbreadth is a traditional unit of length based on the width of a human hand, typically measured from the tip of the thumb to the tip of the little finger when the hand is fully extended. It was commonly used in ancient and medieval times for everyday measurements.
The handbreadth is generally about 3 to 4 inches (approximately 7.5 to 10 centimeters), though the exact length could vary by culture and era.
It served as a practical, easy-to-use measure in tailoring, construction, and daily life before standardized units were established.
The handbreadth is one of several body-based units, like the span and palm, reflecting how humans used their own bodies for measuring.
Summary:
About 3 to 4 inches (7.5 to 10 cm)
Based on the width of an extended hand
Used historically in various cultures
Practical for informal, everyday measurement
Megaparsec
A megaparsec (Mpc) is a unit of distance used in astronomy to measure vast stretches across the universe. One megaparsec equals one million parsecs, or about 3.26 million light-years (1 Mpc ≈ 3.086 × 10¹⁹ kilometers). This unit is commonly used when discussing the distances between galaxies, galaxy clusters, or large-scale structures of the universe. Because the universe is so massive, astronomers need units like megaparsecs to express distances that are too large for even light-years to handle efficiently. The megaparsec is essential in cosmology and is often used when describing the scale of the observable universe.
