index hardness of limestone - uf1
The water hardness is expressed by an index, or total hardness, TH, in degrees, each degree determined by the following formula: 1 degree (°F : French unit) = 4 mg/liter of calcium or 2.43 mg/liter of magnesium or 10 mg of limestone. The waters are classified according to their TH (French TH) 0

Rock Stone Classification and Stone Hardness – Top
2017-7-9 The hardness of stone is measured by Mohs hardness as a unit of calculation, Mohs hardness in the 6~7 (F=14~20) are hard stone, such as Quartzite and Granite; Mohs hardness between 3 to 5 (F=8~14) belong to the medium-hard stone, such as Marble; Mohs hardness in 1~2 (F=2~6) are soft stone, such as limestone
