i cant figure it out i need help

Do you have like, a uhh, Certain equation at all for this??

I cannot help you if you do not answer. 

Hi Tyler,

Welcome to the forum :)

A certain stock measures 0.875 inch in diameter. What does this measure, to the nearest 1/16 inch, with an outside caliper and a scale?

I think I have interpreted your question properly but I am not certain.

0.875/2 = 0.4375

The real measurment would be    \(0.0875\pm0.4375\;inches \)
