Percent to PPM Conversion Calculator

Enter percent:



PPM result:

Conversion:

1 percent (%) = 10000 parts-per million (ppm)

1 parts-per million (ppm) = 0.0001 percent (%)

Conversion Formula:

x(ppm) = 10000 ⋅ x(%)

Example:

Convert 1.7 percent (%) to parts-per million (ppm):

x(ppm) = 10000 ⋅ 1.7% = 17000ppm

Conversion Result:

1.7 percent (%) is equal to 17000 parts-per million (ppm).

1. Introduction

A Percent to PPM Conversion Calculator is a tool that converts concentration values from percentage (%) to parts per million (ppm). This conversion is crucial in chemistry, environmental science, food production, and industrial applications where precise measurements of solution concentrations are required.

2. Understanding Percent and PPM

Percentage (%)

• Definition: Represents parts per hundred (1% = 1 part per 100 parts).

• Formula:

  $$1\mathrm{\%}=\frac{1}{100}=10,000\text{ppm}$$

• Example:
  A 5% saline solution means 5 grams of salt per 100 grams of solution.

Parts Per Million (PPM)

• Definition: Represents 1 part per million parts (1 ppm = 1 mg/kg or 1 µL/L).

• Formula:

  $$1\text{ppm}=\frac{1}{1,000,000}=0.0001\mathrm{\%}$$

• Example:
  A 200 ppm chlorine solution means 200 mg of chlorine per 1 kg of water.

3. Conversion Formula

Since 1% = 10,000 ppm, the conversion from Percent to PPM is:

$$\text{PPM}=\text{Percent (\%)}\times 10,000$$

Example Calculation

If a solution has 0.75% dissolved solids, the PPM value is:

$$0.75\mathrm{\%}\times 10,000=7,500\text{ppm}$$
