The Dead Sea, located between Israel and Jordan, is the saltiest body of water in the world with a salinity level or 330,000 ppm, or 330 ppt, making it nearly 10 times saltier than the world's oceans. Note: PPM and MG/L are the same thing. Water Hardness Chart. Treated (or softened water) = 0-1 GPG (total grains x 17.1 equals ppm) Slightly hard = 1-2 GPG (total grains x 17.1 equals ppm) Medium Hard = 3-7 GPG (total grains x 17.1 equals ppm) Hard = 7-10.5 GPG (total grains x 17.1 equals ppm) Extremely Hard Water = 10.5+ GPG (total grains x 17.1 equals ppm) Hardness is usually expressed in grains per gallon (or ppm) as calcium carbonate equivalent. What is Soft Water? Soft water is defined by American National Standards NSF/ANSI 44 and NSF/ANSI 330 as water containing <1 grain of hardness per gallon (or <17.1 mg/L hardness).

So one parts-per million is equal to 0.0001 percent: 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: x (%) = x (ppm) / 10000 . Example. Convert 300ppm to percent: x (%) = 300ppm / 10000 = 0.03% . Percent to ppm calculation Parts per million - ppm - is commonly used as a dimensionless measure of small levels (concentrations) of pollutants in air, water, body fluids, etc.

Mg/l and PPM are units used to represent the concentration. Mg/l can be abbreviated as milligrams/liter and PPM can be abbreviated as Parts per million. Mg/l can be converted to PPM with the use of specific gravity. Use this online converter for Milligrams Per Liter to Parts Per million conversion. TDS Meter Digital Water Tester, Lxuemlu Professional 3-in-1 TDS, Temperature and EC Meter with Carrying Case, 0-9999ppm, Ideal ppm Meter for Drinking Water, Aquariums and More (LX-TDS1) 4.5 out of 5 stars.

Soft water is defined by American National Standards NSF/ANSI 44 and NSF/ANSI 330 as water containing <1 grain of hardness per gallon (or <17.1 mg/L hardness). Symptoms of Hard Water include: Stiff, dingy laundry The longer water is exposed to a certain stone, the harder it will be. For example, water from an underground aquifer will be harder than water from a river or lake. Water hardness levels are depicted in milligrams per liter (mg/L), parts per million (PPM) or grains per gallon (gpg).

How to convert number in parts-per million (ppm) to percent (%). ppm to percent conversion. 1% = 1/100. 1ppm = 1/1000000. So one parts-per million is equal to 0.0001 percent: 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: x (%) = x (ppm) / 10000 . Example. Convert 300ppm to percent: x (%) = 300ppm / 10000 = 0.03% . Percent to ppm calculation

When we talk about the TSS concentrations, the flow rate of a body of water can be a major factor. Percent to ppm converter How to convert ppm to percent. 1% = 1/100. 1ppm = 1/1000000. So. 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: Hardness is usually expressed in grains per gallon (or ppm) as calcium carbonate equivalent. What is Soft Water?
