Regarding current sensitivity of galvanometer

[logearav]

Homework Statement

a galvanometer with 50 divisions on the scale requires a current sensitivity of 0.1 m A/division. find the galvanometer current?

Homework Equations

I_S= $$\theta/I$$

TO find the galvanometer current, i multiplied 50 with 0.1 to get the galvanometer current, as instructed by my physics teacher. my query is how this multiplication gives galvanometer current. is there any formula/
