Percent weight per volume quick reference
| Percent weight per volume | Milligram per liter | Milligram per deciliter | Kilogram per cubic meter |
|---|---|---|---|
| 1 % w/v | = 10000 mg/L | = 1000 mg/dL | = 10 kg/m³ |
| 10 % w/v | = 100000 mg/L | = 10000 mg/dL | = 100 kg/m³ |
| 100 % w/v | = 1000000 mg/L | = 100000 mg/dL | = 1000 kg/m³ |
| 1000 % w/v | = 10000000 mg/L | = 1000000 mg/dL | = 10000 kg/m³ |
Where the percent weight per volume fits
The next smaller solution concentration unit is the kilogram per cubic meter (kg/m³). 1 % w/v = 10 kg/m³, and 1 kg/m³ = 0.1 % w/v.
The next larger solution concentration unit is the gram per cubic centimeter (g/cm³). 1 % w/v = 0.01 g/cm³, and 1 g/cm³ = 100 % w/v.
