About Converting Quarts to Cubic Exameters
Quart and Cubic Exameter appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Quart is most often used for us recipe measurement (larger liquid volumes).
Formula
cubic exameters = quarts × 9.463529e-58
This factor comes from each unit's defined relationship to the category's base unit: 1 quart equals 0.000946352946 base units, and 1 cubic exameter equals 1e+54 base units, so dividing one by the other gives the direct quart-to-cubic exameter factor of 9.463529e-58.
Simple example
1 qt × 9.463529e-58 = 9.463529e-58 Em3
1 quart = 9.463529e-58 cubic exameters.
Real-world example
10 qt × 9.463529e-58 = 9.463529e-57 Em3
10 quarts = 9.463529e-57 cubic exameters.

History of the Quart
The quart ('quarter' of a gallon) follows the same English wine-gallon lineage as the US gallon, retained by the US after England moved to a different imperial standard in 1824.
Historical origin. Quart was not the invention of a single named person; it developed through the process described above.
