PPB to PPM Conversion Calculator
Enter the PPB (parts per billion) value to convert to PPM (parts per million):
PPB to PPM Formula
The relationship between PPB and PPM is straightforward:
PPM= PPB/1000
Explanation:
1 PPM = 1000 PPB
So, to convert from PPB to PPM, just divide by 1000.
PPB to PPM Conversion Examples
Here are a few quick examples of how PPB converts to PPM:
| PPB Value | Equivalent in PPM |
| 100 ppb | 0.1 ppm |
| 500 ppb | 0.5 ppm |
| 1000 ppb | 1.0 ppm |
| 5000 ppb | 5.0 ppm |
| 10,000 ppb | 10.0 ppm |
These conversions assume dilute aqueous solutions or air, where density is close to 1 g/mL.

FAQs
1. What is PPB?
PPB (parts per billion) is a unit of concentration that describes the number of parts of a substance per billion parts of the total. In water, it is typically measured as µg/L (micrograms per liter).
2. What is PPM?
PPM (parts per million) is a unit of concentration equivalent to mg/L (milligrams per liter) in water.
3. Is 1 PPM always equal to 1000 PPB?
Yes, in most contexts involving liquids or gases, 1 PPM = 1000 PPB, assuming similar densities.
4. Does temperature affect PPB to PPM conversion?
Only slightly. This conversion assumes constant density (like pure water or clean air). In most practical applications, this is accurate enough.
