Fork Springs Conversion

[KDXBADASS]

Trying to get my forks in tune. Fredette Racing says for weight over 200 lbs use the 23 lb fork spring. I really suck at math and all the fork springs I see are measured in KGs. Can anyone hook a Brother up and convert 23 lbs to kgs? I tried the conversion and got 10.432624.........and the numbers ran out. Thank you in advance

The Race Tech web page has a tool for estimating the springs you will need in KG/MM

Went to Fredette Racing and the fork springs they offer are 0.42 0.44 & 0.46 kg?
With the conversion at 10.4 kg has got me totally confused........

23 lbs per inch = 10.4 kg per inch = .41 kg per mm

23 lbs per inch = 10.4 kg per inch = .41 kg per mm

Thank you so much!!!!! Now I feel stupid. I guess when I was in school I shouldn't have ditched classes
so much to go dirt riding? LOL
Thanks again Bro

I did some research and found that XR400 late model fork springs were about 41 42 kgs. I put some of those in with 6mm preload spacers in. Works awesome for me. I am going to give it a smoke test in the woods this weekend. I ran over curbs and hit a bunch of shit out where I keep my bike. Felt like a new bike!!!!
Thanks,
