The History and Evolution of Unit Systems
Unit systems have evolved over millennia. Ancient Egyptians used cubits for building pyramids, while Romans standardized miles. The metric system, born in 1790s France, revolutionized science with base-10 logic. Today, SI units (International System) dominate globally, except in the US where imperial lingers.
Challenges arose in trade, leading to tools like our unit conversion tool. The 1960s space race highlighted issues – NASA's Mars orbiter crashed due to unit mix-ups! Modern converters prevent such disasters. Currency history ties to gold standards, now digitized with APIs for real-time accuracy.
