You mean 95 kgf, I think.

Newtons please.

I agree, Newtons makes much more sense. The SI system is extremely logical.
When teaching dynamics here in the U.S. I had to explain "pounds force"
vs. "pounds mass," and that confusing them could lead to answers being
off by over 30 times. I had to explain the silliness of naming a
conversion factor "g sub c" thereby causing inevitable confusion with
the acceleration of gravity "g." I demanded that students strictly keep
track of units of measurement to avoid the above confusion.
I sang the praises of the SI system, and still do. I said it was so much
more sensible to use different units for Force and Mass: kilograms for
mass, Newtons for force or weight. Why couldn't Americans be that logical?
Then I found that most Europeans were using kgf = "kilograms force."
