One part per million (ppm) denotes one part per 1,000,000 parts, one part in 10 6, and a value of 1 × 10 −6. Percent to PPM Conversion Formula.

How much is 1.5 ppm to ppb? +> with much ♥ by CalculatePlus 1 ppb = 0.001 ppm. 1 x 0.001 ppm = 0.001 Parts Per Million. Always check the results; rounding errors may occur. Definition: In relation to the base unit of [density] => (kilograms per cubic meter), 1 Parts Per Billion (ppb) is equal to 1.0E-6 kilograms-per-cubic-meter, while 1 Parts Per Million (ppm) = 0.001 kilograms-per-cubic-meter. For example, 4 ppm multiplied by is equal to ppb. Best conversion unit for 5 Parts-Per-Million (ppm) We define the "best" unit to convert a number as the unit that is the lowest without going lower than 1.

X (PPM) = X (PPB) / 1000. This means that the number of parts-per million is calculated by dividing the number of parts-per billion by 1000. How many PPM in a PPB? The conversion factor of parts-per billion to parts-per million is 0.001. 1 PPB = 0.001 PPM in terms of parts per million (ppm) or parts per billion (ppb) because the amounts are so First, ppm (parts per million ) and ppb (parts per billion) are defined as `1 ppm = 1/10 6 = 10-6 ` and `1 ppb = 1/10 9 = 10-9 `. So `1 ppm = 1000 ppb or 1 ppb = 10-3 ppm`. The conversion factor depends on the temperature at which you want the conversion (usually 25 degrees Centigrade in the US), as well as the ambient pressure. At an ambient pressure of 1 atmosphere, the general equation is: $$c = { ppmv \times 12.187 \times MW \over 273.15 + t } $$ where: How to convert parts-per-million (ppm) to parts-per-billion (ppb) Check definition.
