   What is hard water ppm?

   • In the US, the unit of water hardness is usually parts per million (ppm) or grains per gallon (GPG). Here is the full water hardness scale (including hard water ppm chart) according to the USGS: mmol/L is a metric unit, usually in use outside of the US. How to tell if you have hard water?

   What is a good water hardness level?

   • Generally, the ideal water hardness level is between 0 – 75 PPM (parts per million). Any reading over 150+ PPM indicates hard water. The higher the number, the harder your water is. Soft water ranges from 0-3 GPG (grains per gallon). Water with a hardness of 3-7 GPG is considered moderately hard.

   Is 0-50 ppm water soft or hard?

   • In general, water that has a rating of 0-50 PPM is considered soft, and water with a rating of 250 PPM is considered hard. Here’s a table showing the PPM ratings and the water hardness: How Hard Is the Water in My Area? Water hardness varies across the country so depending on where you live in the UK, your water hardness will be different.

   What is water hardness in chemistry?

   • By definition, water hardness is the total sum of molar concentrations of calcium ions (Ca 2+) and magnesium ions (Mg 2+). We have there three main units with which we denote water hardness: Parts per million or PPM is equivalent to 1 mg/L CaCO 3 (calcium carbonate).

   What is a hard water rating?

   • Water hardness is measured by a rating of parts per million (PPM) that counts the amount of minerals dissolved into the water. The higher the PPM rating, the harder the water is. In general, water that has a rating of 0-50 PPM is considered soft, and water with a rating of 250 PPM is considered hard.
