Every unit below converts to every other one in the calculator. Values are relative to the base unit, the kilogram per cubic meter (kg/m³).
| Unit | Symbol | System | Value |
|---|---|---|---|
| Kilogram per cubic meter | kg/m³ | SI | Base unit |
| Gram per cubic centimeter | g/cm³ | metric | = 1000 kg/m³ |
| Milligram per liter | mg/L | SI-accepted | = 0.001 kg/m³ |
| Microgram per liter | µg/L | SI-accepted | = 0.000001 kg/m³ |
| Gram per deciliter | g/dL | SI-accepted | = 10 kg/m³ |
| Milligram per deciliter | mg/dL | SI-accepted | = 0.01 kg/m³ |
| Percent weight per volume | % w/v | other | = 10 kg/m³ |
Kilogram per cubic meter quick reference
| Kilogram per cubic meter | Milligram per liter | Microgram per liter | Gram per deciliter |
|---|---|---|---|
| 1 kg/m³ | = 1000 mg/L | = 1000000 µg/L | = 0.1 g/dL |
| 10 kg/m³ | = 10000 mg/L | = 10000000 µg/L | = 1 g/dL |
| 100 kg/m³ | = 100000 mg/L | = 100000000 µg/L | = 10 g/dL |
| 1000 kg/m³ | = 1000000 mg/L | = 1000000000 µg/L | = 100 g/dL |
Among the 7 solution concentration units on this page, the smallest is the microgram per liter (µg/L) and the largest is the gram per cubic centimeter (g/cm³).

About solution concentration units
Mass concentration is the mass of dissolved substance per volume of solution. Its SI unit is the kilogram per cubic meter (kg/m³), which equals one gram per liter. Water testing uses mg/L and µg/L, blood tests use mg/dL and g/dL, and pharmacy uses % w/v (grams per 100 mL).
One mg/dL is exactly 10 mg/L, and 1 % w/v is exactly 10 g/L. In dilute water solutions, 1 mg/L is close to 1 ppm and 1 µg/L close to 1 ppb, because a liter of water has a mass of about 1 kg. For other liquids or strong solutions they differ.
Frequently asked questions
- Is mg/L the same as ppm?
- Nearly, for dilute solutions in water. ppm is a ratio of masses, while mg/L is mass per volume; they match only when one liter of the solution has a mass of about 1 kg.
- How do I convert mg/dL to mg/L?
- Multiply by 10. A deciliter is one tenth of a liter, so 100 mg/dL is 1000 mg/L, or 1 g/L.
- What does 0.9 % w/v mean?
- 0.9 grams of solute in every 100 mL of solution, which is 9 g/L. Normal saline is 0.9 % w/v sodium chloride.
- How many milligrams per liter are in one kilogram per cubic meter?
- One kilogram per cubic meter = 1000 mg/L (milligrams per liter).
- How many micrograms per liter are in one kilogram per cubic meter?
- One kilogram per cubic meter = 1000000 µg/L (micrograms per liter).
- How many grams per deciliter are in one kilogram per cubic meter?
- One kilogram per cubic meter = 0.1 g/dL (grams per deciliter).
