Spring Wire Diameter formulas

\(\large{ d = \frac{ D_o - D_i }{ 2 }  }\)

\(\large{ D_o = 2 \; d + D_i }\)

\(\large{ D_i = D_o - 2 \; d  }\)

Symbol English Metric
\(\large{ d }\) = wire diameter \(\large{ in }\) \(\large{ mm }\)
\(\large{ D_i }\) = inner diameter \(\large{ in }\) \(\large{ mm }\)
\(\large{ D_o }\) = outer diameter \(\large{ in }\) \(\large{ mm }\)
