Determination of uniaxial compressive strength (UCS) of intact rock is an important mechanical parameter required for many engineering projects. In some engineering projects, for example, well drilling has been accomplished for petroleum. The requirement of deep well to take samples to obtain rock core sample for determination of UCS is a difficult task. On the other hand, determination of this parameter is essential in order to analyze well wall stability and well development program. Therefore, the idea of using drilling cuttings is proposed for determination of UCS. In this paper, in order to develop relationship between UCS and single compressive strength (SCS) 7 block sample of microcrystalline limestone from Asmari formation were used. Then UCS test was performed and uniaxial compressive strength was determined. Next, these samples were crushed and 420 single particles were prepared. Then SCS for each particle was determined. Since the shape of particles affects particle strength, shape of particles was modified.  The total particles used for determination of SCS were spherical. In order to study the effect size of particle, particles with diameters 2, 3 and 4 millimeters were prepared and the SCS for each particle has been determined. With the increase of diameter of particles, the SCS has been increased too. In order to eliminate the effect of size of particles, it is defined variable size and strength and proposed chart between them. Coefficient of correlation between SCS and UCS is more than 0.91 which indicates a high correlation between them.
