Parts Per Million (ppm) Converter for Gases. This converter calculates the measured value in units of [ppm] into units of [mg/m 3] and visa versa. The unit ppm is used in several branches in different ways. The use of ppm therefore has to be specified in the input fields below, in the way it should convert the value with the proper unit.

This information can be substituted in the formulas for converting between mg/m 3 and ppm. where the value of R is 62.4 L torr/mol K when the temperature (T) is in kelvins (K), (K =273.16 + T°C), the pressure is expressed in units of mm Hg (1 mmHg = 1 torr), and the volume is in liters. Water hardness follows these guidelines: 0 - 4 dH, 0 - 70 ppm : very soft 4 - 8 dH, 70 - 140 ppm : soft 8 - 12 dH, 140 - 210 ppm : medium hard 12 - 18 dH, 210 - 320 ppm : fairly hard 18 - 30 dH, 320 - 530 ppm : hard higher : liquid rock (Lake Malawi and Los Angeles, CA) General hardness is the more important of the two in biological processes. 2019-10-01 concentration is 4 ppm? 8) What mass of nickel is in a 2.4 Kg sample of propanol if the concentration is 20 ppb? 9) What mass of solution would be needed to deliver 3.0 mg of a drug if the concentration of the drug in the solution was 3.5%. 10) What is the concentration, in ppm, if 0.808 grams of CaCl 2 is dissolved in 250.0 ml of water.

You can perform a PPM conversion easily provided you have two quantities in the same unit (or that you can convert into the same unit) or a percentage value. PPM means "parts per million," so to calculate it you divide the amount of the solute by the total amount of solution, them multiply by 10^6. Percent to PPM Converter.

4 ppm

På samma vis som procent så beskriver både promille och ppm hur stor del som något är av en helhet (det hela). Bägge begreppet används istället för procent om andelen är mycket liten. ppm↔lb/gal (UK) 1 lb/gal (UK) = 99776.397913856 ppm ppm↔lb/ft3 1 lb/ft3 = 16018.46336974 ppm ppm↔lb/gal (US) 1 lb/gal (US) = 119826.42730074 ppm Exempel 4: Hur många procent är 40 till procent? Lösning: Börja med att göra om promilletalet till bråkform: 40 = 40/1000. Skriv sedan tusendelarna som hundradelar: 40/1000 = 4/100.

PPM stands for Parts Per Million, it is a chemical term used to represent a very low concentration of a solution. Milliliter and Liter are units to represent volume of liquids. 1 milliliter is equal to 1000 liters. [4] Rekommendationer har gjorts för max- och minvärden för kalcium (40–80 ppm) och magnesium (20–30 ppm) i dricksvatten, och en total hårdhet uttryckt som summan av kalcium- och magnesiumkoncentrationer på 2 – 4 mmol/L.
