Monetary Conversion

The following table is a commodity price index to compare real money values over time. The base year is 1860 (100). To convert 1860 dollars into 1999 dollars, for example, you would determine the ratio between 1999 dollars and 1860 dollars (1,997-to-100, or 19.97-to-1), and multiply the 1860 dollar amount ($500) by the ratio (19.97). Thus, $500 in 1860 dollars is approximately $9,985 in 1999 dollars ($500 x 19.97).


Note: Any conversion using this table is an approximation only. This table provides only the central tendency in the movement of prices of all commodities. The prices of some commodities have changed more substantially and those of others have changed less than this index indicates.
