Units & Measurement — UPSSSC PET Preparation
This question tests your understanding of Units & Measurement, a key topic in the UPSSSC PET General Knowledge section. The detailed solution above uses a step-by-step approach to show the reasoning, and where available, a shortcut that helps you solve similar questions in under 90 seconds during the actual exam.
This topic covers physical quantities and their units: the SI system and its seven base units, derived units, units named after scientists, conversion between units, measuring instruments, and the difference between scalar and vector quantities. Questions commonly ask for the SI unit of a quantity (the newton for force, the pascal for pressure and the joule for energy), what an instrument measures (a barometer measures atmospheric pressure, and a hygrometer measures humidity), and whether a quantity is a scalar or a vector. One light-year is a unit of distance, not time. Practise the units and measurement questions below, written in the style of the general awareness sections of exams such as SSC, banking, railways, CUET GAT, MAH CET and CLAT. Each question comes with a detailed explanation that adds related facts, so every question helps you revise more than one point.
