Coinage with explicit denominations in decimal fractions of the franc also began in 1795. Decimalization of the franc was mandated by an act of 7 April 1795, which also dealt with the decimalization of weights and measures. France led the world in adopting the metric system and it was the second country to convert from a non-decimal to a decimal currency, following Russia's conversion in 1704, and the third country to adopt a decimal coinage, also following the United States in 1787. France's first decimal coinage used allegorical figures symbolizing revolutionary principles, like the coinage designs the United States had adopted in 1793.
