Calculating components per billion (ppb)
To calculate ppb, we will multiply the focus of a substance in mg/L by 1,000,000.
ppb = focus in mg/L * 1,000,000
For instance, if the focus of a substance is 1 mg/L, the calculation can be:
| Formulation | Calculation | Instance |
|---|---|---|
| ppb = focus in mg/L * 1,000,000 | Calculate 1 mg/L focus in ppb | focus = 1 mg/L * 1,000,000 = 1,000,000 ppb |
Vice Versa
Once we need to calculate ppm from ppb, we will divide the focus of a substance in ppb by 1,000,000.
ppm = focus in ppb / 1,000,000
For instance, if the focus of a substance is 1,000,000 ppb, the calculation can be:
| Formulation | Calculation | Instance |
|---|---|---|
| ppm = focus in ppb / 1,000,000 | Calculate 1,000,000 ppb focus in ppm | focus = 1,000,000 ppb / 1,000,000 = 1 ppm |
