Generally people use G(gram )or N (Newton force) to define all kinds force concepts. Please also refer to our blog how to test the life of metal dome .
And click ratio, someone also name it click feeling (CC) has a equation to define: CC(%)=(CP-CL)/CP*100%, this CC result(click ratio) is commonly required at 35%~6o%, if the click ratio is too high then it will affect the life cycle of metal dome.
