About Converting Ounces per Cubic Millimeter to Kilograms per Teaspoon
Ounce per Cubic Millimeter and Kilogram per Teaspoon 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. Both are mass per volume density units.
Formula
kilograms per teaspoon = ounces per cubic millimeter × 139.732576703
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic millimeter equals 28349523.125 base units, and 1 kilogram per teaspoon equals 202884.136211 base units, so dividing one by the other gives the direct ounce per cubic millimeter-to-kilogram per teaspoon factor of 139.732576703.
Simple example
1 oz/mm3 × 139.7325767 = 139.7325767 kg/tsp
1 ounce per cubic millimeter = 139.7325767 kilograms per teaspoon.
Real-world example
1,000 oz/mm3 × 139.7325767 = 139,732.5767 kg/tsp
1,000 ounces per cubic millimeter = 139,732.5767 kilograms per teaspoon.

Frequently asked questions
How many kilograms per teaspoon are in 1 ounce per cubic millimeter?
1 ounce per cubic millimeter equals 139.7325767 kilograms per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per cubic millimeter to kilogram per teaspoon?
Multiply the ounce per cubic millimeter value by 139.7325767. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per teaspoon back to ounce per cubic millimeter?
Use the reverse factor: 1 kilogram per teaspoon equals 0.0071565273 ounces per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per cubic millimeter?
Ounce per Cubic Millimeter (oz/mm3) is a unit of density.
What is a kilogram per teaspoon?
Kilogram per Teaspoon (kg/tsp) is a unit of density.
Is the ounce per cubic millimeter to kilogram per teaspoon conversion exact?
Yes. Both ounce per cubic millimeter and kilogram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 139.7325767 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
