Uttryckt i procent är 1 ppb = 0,000 000 1 % det vill säga 10–7 %. Svenska och internationella standarder avråder från måttet. Istället bör andelen anges i andelar 

Vanligtvis används delar per miljon ( ppm , 10 −6 ), delar per miljard ( ppb , 10 −9 ), delar per biljon ( ppt , 10 −12 ) och delar per kvadrillion 

Use the calculators below to convert between ppm and Hz. The equation for this relationship is, where ppm is the peak variation (expressed as +/-), f is the center frequency (in Hz), df is the peak frequency variation (in Hz), and 10 6 is 1000000 (e.g. one million). Enter numbers below as integers, decimals, or use scientific notation (for 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`.

Így például a ppb elnevezés nem lenne egyértelmű. 1999-ben javaslat érkezett az Uno (U, egy egész) SI mennyiség bevezetésére, melyhez SI-prefixumokat lehetne ragasztani.

So. 1ppm = 1000ppb. The number of parts-per million x ppm is equal to the number of parts-per billion x ppb divided by 1000: Ppm to ppb. This converter can convert parts-per-million(ppm) to parts-per-billion(ppb), negative and decimal numbers are also supported. Type your number then click Convert now button. It is also possible to convert ppb to ppm Ppb to ppm converter. 1 parts-per billion = 1/10 9 = 10-9 1 parts-per-million = 1/10 6 = 10-6; we get: 1ppm = 1000ppb so 1ppb = 0.001ppm 8.1 ppb = 0.0081 ppm : 9.1 ppb = 0.0091 ppm : 10.1 ppb = 0.0101 ppm : 11.1 ppb = 0.0111 ppm : 12.1 ppb = 0.0121 ppm : 13.1 ppb = 0.0131 ppm : 14.1 ppb = 0.0141 ppm : 15.1 ppb = 0.0151 ppm : 16.1 ppb = 0.0161 ppm : 17.1 ppb = 0.0171 ppm : 18.1 ppb = 0.0181 ppm : 19.1 ppb = 0.0191 ppm : 21 ppb = 0.021 ppm 31 ppb = 0.031 ppm 41 ppb = 0.041 ppm 51 ppb = 0.051 ppm 10 ppb = 0.01 ppm: 20 ppb = 0.02 ppm: 30 ppb = 0.03 ppm: 40 ppb = 0.04 ppm: 50 ppb = 0.05 ppm: 60 ppb = 0.06 ppm: 70 ppb = 0.07 ppm: 80 ppb = 0.08 ppm: 90 ppb = 0.09 ppm: 100 ppb = 0.1 ppm: 200 ppb = 0.2 ppm: 300 ppb = 0.3 ppm: 400 ppb = 0.4 ppm: 500 ppb = 0.5 ppm: 600 ppb = 0.6 ppm: 700 ppb = 0.7 ppm: 800 ppb = 0.8 ppm: 900 ppb = 0.9 ppm: 1000 ppm to μg/kg (part per million to microgram/kilogram) 3 mg/kg to ppb (milligrams/kilogram to parts per billion) g/kg to mg/kg (gram/kilogram to milligram/kilogram) 100 microliter/milliliter to percent (μl/ml to pct) mg/kg to percent (milligram/kilogram to pct) percent to … การแปลงหน่วย ระดับ % volume ถึง ระดับ ppm, ppb, ppt และระดับหน่วย SI .

This tutorial gives a bri 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. Easily convert Parts Per Million (ppm) to Decimal using this free online unit conversion calculator. What is ppm? ppm is an abbreviation of parts per million.
