How to read your Mass Concentration in Solution result

Mass concentration is mass of solute per volume of solution. 1 kg/m³ equals 1 g/L and 1 mg/mL. In dilute water solutions, 1 mg/L is commonly treated as 1 part per million and 1 µg/L as 1 part per billion.

Common mistakes when calculating Mass Concentration in Solution

  • Treating mg/L as ppm for solutions that are not dilute water-like solutions.
  • Mixing mg/L and µg/L, which differ by 1,000.
  • Mixing mass concentration with molar concentration, which needs the molar mass.

Mass Concentration in Solution FAQ

How many g/L is 1 kg/m³?

1 kg/m³ is exactly 1 g/L.

How many mg/L is 1 g/L?

1 g/L is 1,000 mg/L.

Is mg/L the same as ppm?

For dilute aqueous solutions, 1 mg/L is approximately 1 ppm, because a litre of water has a mass near 1 kg.

What is the base unit for mass concentration in solution?

This converter uses kilogram per cubic meter (kg/m³) as the common base unit: every value is first converted to it and then to the target unit.

How do I convert between two mass concentration in solution units?

Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.

How many grams per liter are in 1 kilogram per cubic meter?

1 kg/m³ = 1 g/L.

How many milligrams per liter are in 1 kilogram per cubic meter?

1 kg/m³ = 1,000 mg/L.

How many micrograms per liter are in 1 kilogram per cubic meter?

1 kg/m³ = 1,000,000 µg/L.

Which mass concentration in solution units does this converter support?

It covers 9 units: kilogram per cubic meter (kg/m³), gram per liter (g/L), milligram per liter (mg/L), microgram per liter (µg/L), milligram per milliliter (mg/mL), gram per milliliter (g/mL), kilogram per liter (kg/L), Grain per US gallon (gr/gal), Pound per US gallon (lb/gal).

How accurate is the mass concentration in solution converter?

Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
