| Solution | Concentration | Equivalent |
|---|---|---|
| Saline (medical) | 0.9% w/v | 9 g/L or 9000 ppm |
| Drinking water (WHO limit) | 500 ppm TDS | 0.05% or 0.5 g/L |
| Concentrated HCl | 12 M | ~37% w/v |
| Ethanol (wine) | 12% v/v | ~96 g/L |
| Glucose in blood | 5 mM | ~0.9 g/L or 900 mg/L |
Moles of solute per liter of solution. Most common unit in chemistry. 1M = 1 mol/L. Depends on molecular weight of the substance.
Mass of solute per 100 mL of solution. 1% w/v = 1 g per 100 mL = 10 g/L. Common in medical and pharmaceutical contexts.
Milligrams of solute per liter (mg/L) for aqueous solutions. 1 ppm = 1 mg/L = 0.001 g/L. Used for trace concentrations in water quality.
Micrograms per liter (µg/L). 1 ppb = 1 µg/L = 0.001 mg/L. Used for very low concentrations like pollutants.
Direct mass/volume units. 1 mg/mL = 1 g/L. Commonly used in laboratory settings and pharmaceutical formulations.
Important Note: This converter uses a simplified assumption of 1M = 10% w/v. In reality, molarity conversions depend on the molecular weight of the specific substance. For precise calculations, multiply molarity by the molecular weight to get g/L.
Percent to g/L: % w/v × 10 = g/L
PPM to mg/L: 1 ppm = 1 mg/L (in water)
PPB to µg/L: 1 ppb = 1 µg/L
Molarity to g/L: M × Molecular Weight = g/L
mg/mL to g/L: 1 mg/mL = 1 g/L
PPM to PPB: 1 ppm = 1000 ppb
