Where did you get this information from? If it was your water company, what unit did they give? It is unlikely to be ppm but it could be mg/l calcium carbonate or mg/l calcium (and I've even seen mg/l calcium oxide).
If it was not your water company can I ask you to look on their website for hardness. You do need a number - and the unit - though some water companies no longer give a number, just words which can be misleading.
It was my water suppliers website. in water hardness it says "soft", then theres hardness clarke, which I thought was the value of the hardness, which is 1.61. Like I said I'm trying to confirm if it's the same as GH. To be honest I think I'm just over complicating things for myself, as I tend to do. here is some screenshots, you can no doubt make more sense of it then I can.
