Okay so quickly, without google, how many gallons are there in a cubic yard? Now for the people who know metric it's fairly trivial to calculate how many liters there are in a cubic meter. A liter is defined as being one cubic decimeter. A decimeter being one step down from a meter means for cubic measurements it's a factor 1000. one cubic meter multiplied by a thousand is 1000 cubic decimeters or, equivalently, 1000 liters. Note how in both examples you start with nice round numbers. I havent cherry picked a starting point that ends up nicely in metric.
