Convert Kilograms per Cubic Meter to Grams per Milliliter

What are kilograms per cubic meter and grams per milliliter?

Kilograms per cubic meter is the SI unit of density; water is about 1,000 kg/m³. Grams per milliliter equals grams per cubic centimeter; water is 1 g/mL. For reference: water is 1,000 kg/m³ (1 g/cm³), and steel is about 7,850 kg/m³.

How to convert kilograms per cubic meter to grams per milliliter

1 kg/m³ = 0.001 g/mL. To convert, multiply the number of kilograms per cubic meter by 0.001. For example, 5 kg/m³ = 0.005 g/mL, and 20 kg/m³ = 0.02 g/mL. To go the other way, multiply grams per milliliter by 1,000 (since 1 g/mL = 1,000 kg/m³).

FAQ

What is 1 kg/m³ in g/mL?

1 kg/m³ = 0.001 g/mL. To convert any amount, multiply the number of kilograms per cubic meter by 0.001.

How do I convert grams per milliliter back to kilograms per cubic meter?

Go the other way: 1 g/mL = 1,000 kg/m³, so multiply grams per milliliter by 1,000 to get kilograms per cubic meter.

Is a kilograms per cubic meter bigger than a grams per milliliter?

No — 1 kg/m³ is the smaller unit, equal to 0.001 g/mL (it takes 1,000 kg/m³ to make one g/mL).

Are these density conversions exact?

They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
