Dosing with KCl

It states in Rex's web page
1g potassium sulphate raises potassium levels in 10 gallons water by 11.82ppm.

I don't have potassium sulphate but do have potassium chloride.

Am i correct to assume then that 2g of potassium chloride will raise potassium levels in 10 gallons water by the same amount??

If not what should the dosage be?
