About Converting Kilograms per Cubic yard to Metric tons per Cubic Millimeter
Kilogram per Cubic yard and Metric ton per Cubic Millimeter both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Kilogram per Cubic yard is most often used for can be used to express the density of bulk construction materials such as gravel, soil, or aggregate — in practice, us construction and landscaping references more commonly express this as tons per cubic yard or pounds per cubic foot.
Formula
metric tons per cubic millimeter = kilograms per cubic yard × 1.307951e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per cubic yard equals 1.30795061931 base units, and 1 metric ton per cubic millimeter equals 1000000000000 base units, so dividing one by the other gives the direct kilogram per cubic yard-to-metric ton per cubic millimeter factor of 1.307951e-12.
Simple example
1 kg/yd3 × 1.307951e-12 = 1.307951e-12 t/mm3
1 kilogram per cubic yard = 1.307951e-12 metric tons per cubic millimeter.
Real-world example
1,000 kg/yd3 × 1.307951e-12 = 1.307951e-9 t/mm3
1,000 kilograms per cubic yard = 1.307951e-9 metric tons per cubic millimeter.
