Historical Currency Converter

Estimate the purchasing power of historical currencies relative to modern values. Disclaimer: Historical economics are notoriously difficult to calculate due to completely different baskets of goods (e.g., pre-industrial societies spent roughly 70-80% of income on food). These figures are broad estimates based on labor value and commodity prices.
