About Converting Cubic yards to Cubic Kilometers
Cubic yard and Cubic Kilometer 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. Cubic yard is most often used for us construction material estimating (concrete, mulch, topsoil, gravel — commonly sold by the cubic yard).
Formula
cubic kilometers = cubic yards × 7.645549e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard equals 0.764554857984 base units, and 1 cubic kilometer equals 1000000000 base units, so dividing one by the other gives the direct cubic yard-to-cubic kilometer factor of 7.645549e-10.
Simple example
1 yd3 × 7.645549e-10 = 7.645549e-10 km3
1 cubic yard = 7.645549e-10 cubic kilometers.
Real-world example
10 yd3 × 7.645549e-10 = 7.645549e-9 km3
10 cubic yards = 7.645549e-9 cubic kilometers.
