Did You Know?
The metric system (SI) is used by every country in the world for science and by most countries for everyday use. Only the United States, Liberia, and Myanmar primarily use non-metric units in daily life.
The International System of Units (SI) defines 7 base units: the second (time), metre (length), kilogram (mass), ampere (electric current), kelvin (temperature), mole (amount), and candela (luminous intensity). All other units are derived from these.
Unit conversion errors have caused real-world disasters: NASA lost the Mars Climate Orbiter in 1999 because one team used metric units and another used imperial units — a $327 million mistake.
