Adjust transportation services prices for inflation

Start with the inflation rate formula:

CPI in 1940 / CPI in 1938 * 1938 USD value = 1940 USD value

Then plug in historical CPI values from above. The CPI for Transportation services was 11.780 in the year 1938 and 11.800 in 1940:

11.800 / 11.780 * $1 = $1

Therefore, according to U.S. Bureau of Labor Statistics, $1 in 1938 has the same "purchasing power" as $1 in 1940 (in the CPI category of Transportation services).
