Currency Conversion Guide
Complete guide to understanding currency measurements
Overview
Currency represents the medium of exchange for goods and services. While not a physical unit like length or weight, currency conversion is essential for international trade, travel, and global economics.
Historical Background
Currency systems date back thousands of years, evolving from barter to coins (Lydia, 7th century BCE) to paper money (China, 7th century CE). The US dollar became the world's reserve currency after World War II with the Bretton Woods agreement. Exchange rates fluctuate based on economic factors, inflation, interest rates, and geopolitical events. Modern digital currencies like Bitcoin represent a new evolution in monetary systems. The Euro, introduced in 1999, unified currencies across multiple European nations.
