I am using NiMn2O4 as an anode material for li ion half cell. For GCD I have c rates like C/10, C/5, C/2 and C. For each C- rate I have calculated current value by using 900mAh/g theoretical capacity value. Now I want to mention this values in A/g like researchers mentioned in literature.

Current Density=Applied value of current/Active material of anode

Is this the formula ?

When I calculated it seems like I am committing some mistake here.

Thank you very much for consideration
