Funny thing. I just bought a test kit for my fish tank that reports Hardness in German Degrees, when I'm used to PPM. So off I went in search of conversions...

I found that one Grain/US Gallon (17.8571 ppm) was was 0.958 German degrees

I also found that the French Degree (F°) is defined as 10 mg/ CaCO+3 per 1000 ml water, and that One Grain per US Gallon was equal to 1.71 French Degrees.
