Different Systems of Units
Various measurement systems coexist globally, each tailored to historical or regional needs. The metric system uses base-10 multiples for simplicity, while imperial relies on divisions like 12 inches per foot. EazyCalc bridges these by supporting conversions between metric (SI), imperial (US/UK), and others like nautical or avoirdupois, aiding international trade and science.
History of the Pound
The pound originated in medieval England as a unit of weight tied to silver coins, standardized at 0.453592 kilograms in 1824 by the British Weights and Measures Act. It evolved from Roman libra and Anglo-Saxon pend, with the avoirdupois pound (used today) differing from the troy pound for precious metals. Today, EazyCalc converts pounds accurately to grams or kilograms for modern applications.
Brief History of the Metric System
Proposed in 1670 by Gabriel Mouton and formalized during the French Revolution in 1795, the metric system aimed for universal rationality with meter as 1/10-millionth of Earth's meridian quadrant. Adopted internationally via 1875 Treaty of the Meter, it underpins SI units used in 95% of nations. EazyCalc handles metric conversions effortlessly, reflecting its dominance in science and commerce.
