Convert Milligram per Liter to Specific Gravity

Type the number of milligrams per liter that you wish to convert to specific gravity.

1 mg/L (milligrams per liter) = 1e-6 SG (specific gravity)

How to Convert Milligrams per Liter to Specific Gravity

The milligram per liter and specific gravity are both units of density. By definition, 1 specific gravity equals exactly 1000000 milligrams per liter. This means to convert milligrams per liter to specific gravity, you divide by 1000000.

Formula

specific gravity = milligrams per liter ÷ 1000000

Step-by-Step Example

Convert 5 mg/L to specific gravity:

1
Convert 5 mg/L to specific gravity

We need to convert milligrams per liter to specific gravity

2
Apply the formula

Since 1 SG = 1000000 mg/L, divide by 1000000

5 ÷ 1000000 = 5e-6

Answer

5 mg/L = 5e-6 SG

About These Units

Milligram per Liter (mg/L)

Milligrams per liter (mg/L) measures trace concentrations, approximately equal to ppm (parts per million) in water. Used for water quality: chlorine 1-4 mg/L, fluoride 0.7 mg/L, lead <15 mg/L. Also measures pollutants and dissolved minerals.

Specific Gravity (SG)

Specific gravity (SG) is the dimensionless ratio of a substance's density to water at 4°C. Water = 1.0 by definition. Gasoline: 0.72-0.78. Honey: 1.4. Mercury: 13.6. Gold: 19.3. Also called relative density. Objects with SG < 1 float in water.
