All file types, file format descriptions, and software programs listed on this page have been individually researched and verified by the FileInfo team.We strive for 100% accuracy and only publish information about file formats that we have tested and validated. Because the names of numbers 10 9 and larger are not uniform worldwide, it is best that they be avoided entirely (in most countries, 1 billion = 1 × 10 12, not 1 × 10 9 as in the United States); the preferred way of expressing large numbers is to use powers of 10. This ambiguity in the names of numbers is one of the reasons why the use of ppm, ppb, ppt, and the like is deprecated. How to convert ppm to ppb. ppm and ppb are defined as: 1ppm = 1/10 6 = 10 -6. 1ppb = 1/10 9 = 10 -9. So. 1ppm = 1000ppb.

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 Dilution Calculator - ppb, ppm, ppt, pph Meant to be used in both the teaching and research laboratory, this calculator (see below) can be utilized to perform dilution calculations when working with solutions having the following concentration units: parts per billion ( ppb ), parts per million ( ppm ), parts per thousand ( ppt ), and parts per hundred ( pph, % ).

Concentrations can also be expressed as parts per million (ppm) or parts per billion (ppb) by using a conversion factor. This conversion factor is based on the molecular weight of the chemical and it is different for every chemical. The temperature of the atmosphere also has an influence on the calculation.
