Solution Concentration Converter — g/L, mg/L, ppm, ppb
Convert between 8 units of solution concentration — g/L, mg/L, μg/L, ng/L, g/dL, mg/dL, ppm, and ppb. WHO safe drinking water allows arsenic up to 10 ppb (10 μg/L). Blood alcohol is measured in g/dL (legal limit typically 0.08 g/dL). Used in water treatment, environmental monitoring, pharmaceutical preparation and food science.
About the Solution Concentration Converter
Concentration expresses how much solute is dissolved in a given amount of solution or solvent. Mass concentration (g/L, mg/L) is widely used in environmental science, water treatment, and pharmacy. Parts per million (ppm) and parts per billion (ppb) describe very low concentrations such as pollutants in water or air. Percent weight-per-volume (% w/v) is standard in pharmaceutical preparations and food science.
- ›Safe drinking water allows arsenic up to 10 ppb (10 μg/L) according to WHO guidelines
- ›Blood alcohol concentration (BAC) is measured in g/100 mL — 0.08 g/100 mL is the legal limit in many countries
- ›Seawater contains approximately 35 g/L of dissolved salts (mainly NaCl)
- ›One ppm in water = 1 mg/L ≈ 1 mg per kg of water
Frequently Asked Questions
What units does the Solution Concentration Converter — g/L, mg/L, ppm, ppb support?
The Solution Concentration Converter — g/L, mg/L, ppm, ppb supports multiple units with instant conversion. Convert between 8 units of solution concentration — g/L, mg/L, μg/L, ng/L, g/dL, mg/dL, ppm, and ppb. WHO safe drinking water allows arsenic up to 10 ppb (10 μg/L). Blood alcohol is measured in g/dL (legal limit typically 0.08 g/dL). Used in water treatment, environmental monitoring, pharmaceutical preparation and food science. All results use SI-validated constants accurate to 8 significant figures.
