Units and Measurement: SSC CGL Physics
Units, Measurement and Dimensions has seven questions in the SSC CGL Tier I bank: two from the 2023 shifts and five from the 2024 shifts, and none from the 2025 shifts. Nearly all ask which unit goes with which quantity, or which unit in a list is out of place. One page gives the matches, the units that mislead, and the vernier calliper.
The handout has every subtopic, worked example, formula and trap with answers shown. The formula sheet is the chapter’s formulas and traps alone, on one page.
