Kilograms per cubic meter to Grams per milliliter (kg/m³ to g/mL)

Convert kilograms per cubic meter to grams per milliliter: 1 kg/m³ = 0.001 g/mL. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.

Formula

1 kg/m³ = 0.001 g/mL

grams per milliliter = kilograms per cubic meter × 0.001 — reverse: kilograms per cubic meter = grams per milliliter × 1000

The factor is derived from the SI definitions of both units (base unit: kg/m3) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.

Worked examples

5 kg/m³ = 0.005 g/mL
12.5 kg/m³ = 0.0125 g/mL
100 kg/m³ = 0.1 g/mL

FAQ

How many grams per milliliter are in one kilogram per cubic meter?

1 kg/m³ = 0.001 g/mL. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.

What is the formula to convert kilograms per cubic meter to grams per milliliter?

Multiply the value in kilograms per cubic meter by 0.001: grams per milliliter = kilograms per cubic meter × 0.001. For example, 5 kg/m³ = 0.005 g/mL.

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

Multiply by the inverse factor 1000 (kilograms per cubic meter = grams per milliliter × 1000), or use the grams per milliliter-to-kilograms per cubic meter page.
