It measures the mass of the chemical substance or concentration per unit weight of water/solid or volume of one part of gas. One part per million is equal to 0.000001 units. In standard units, then, 1 PPM translates to 1/1,000th of a gram divided into 1,000 milliliters, since 1,000 times 1,000 equals 1 million.

A degree of General Hardness ( dGH or 'German degree (°dH, deutsche Härte ))' is defined as 10 mg/L CaO or 17.848 ppm. A Clark degree (°Clark) or English degrees (°e or e) is defined as one grain (64.8 mg) of CaCO 3 per Imperial gallon (4.55 litres) of water, equivalent to 14.254 ppm.

Titrating to end point of 4.5 pH gives CO3 and HCO3 total. Formula: concentration (mg/m 3) = 0.0409 x concentration (ppm) x molecular weight For example: 100 ppm of NH 3 (17.03 g/mol) 0.0409 x 100 ppm x 17.03 = 69.652 mol/Lとppmの変換（換算）方法 計算問題を解いてみよう . 科学的な解析を行うときに、単位の換算を行うことが多くあります。 mg/l to ppm to tds to mmol/l to meq to EC to μS (microSiemens) TDS and electrical conductivity.

1mmol is 1 thousandth of a mole, which is the molecular weight of your substance in grams. ppm↔mg/L 1 ppm = 1 mg/L. ppm↔mg/mL 1 mg/mL = 1000 ppm. ppm↔mg/tsp 1 mg/tsp = 5000 ppm. ppm↔ug/uL 1 ug/uL = 1000 ppm.

Hence Molarity = 400ppm divided by 40,000mg/mol = 0.01M Ppm (parts per million) to % (parts per hundred) Divide the ppm amount by 1,000,000 and multiply by 100 to get %. e.g. : 2008-04-08 Major betydelser av mmol/L Följande bild presenterar de mest använda betydelserna av mmol/L.
