2004 June 27 In USMA 30220 David wrote "you can also use grams-force". No you can not, not if you use SI.
Standard SI10 says in 3.3.3.1 "Do not use old metric units such
as ... kilogram-force per square centimeter"
and in C.6.1 "The kilogram-force ... is not used."
Use of gram-force is a way to degrade accuracy in measurement and
continues the confusion of mass and weight.
