How to Calculate Between μg/L and mg/L

The μg/L to mg/L and mg/L to μg/L Calculator converts between micrograms per liter (μg/L) and milligrams per liter (mg/L) for water solutions. The formulas are:

Where:

• \( mg/L \): Milligrams per liter, a unit of mass concentration.
• \( \mu g/L \): Micrograms per liter, a unit of mass concentration.

Select the conversion direction, enter the input value, and calculate the result.

Note: The conversion assumes 1 mg/L = 1000 μg/L, valid for water solutions where 1 liter weighs approximately 1 kg.

Using the μg/L and mg/L Mutual Conversion Calculator

This calculator is useful for water quality analysis, such as measuring contaminants or dissolved substances in water, supporting bidirectional conversions.

Select the direction (μg/L to mg/L or mg/L to μg/L), input the concentration value. The calculator outputs the converted value.

Example 1: For a concentration of 1500 μg/L to mg/L.

1. Direction: μg/L to mg/L
2. Input: \( 1500 \)
3. Calculation: \( mg/L = 1500 / 1000 = 1.5 \)
4. Result: \( 1.5 \, \text{mg/L} \)

Example 2: For a concentration of 2.5 mg/L to μg/L.

1. Direction: mg/L to μg/L
2. Input: \( 2.5 \)
3. Calculation: \( \mu g/L = 2.5 \times 1000 = 2500 \)
4. Result: \( 2500 \, \text{μg/L} \)

Use this tool for quick bidirectional conversions in environmental or chemical analysis.

Common FAQ

Below are frequently asked questions about μg/L and mg/L conversions:
