Given that \[p\,=\] chain pitch C = Centre distance N, n = number of teeth on large and small sprocket respectively, The length of chain in terms of pitches can be approximated by:

\[\frac{2C}{P}+\left[ \frac{N+n}{2\pi } \right]\frac{p}{C}\]

\[\frac{2C}{P}+\frac{N+n}{2p}{{\left[ \frac{N-n}{2p} \right]}^{2}}\,\frac{p}{C}\]

Given that \[p\,=\] chain pitch C = Centre distance N,
