Length / diameter of the solid cylinder = Observed reading +Zerocorrection
= {MSR + (VSC x LC)} + ZC
MSR = Main Scale Reading
VSC = Vernier Scale Coincidence
LC = Least Count
ZC = Zero Correction
Vernier Scale Reading (VSR) = V e r n i e r S c a l e C o i n c i d e n c e(VSC) x Least Count (LC)Observed Reading (OR) = Main Scale Reading (MSR) +Vernier Scale Reading (VSR)Correct Reading(CR) = O b s e r v e d R e a d i n g ( O R ) + Z e r oCorrection (ZC)
