NCERT Handwritten Notes Class 11 Physics Chapter 1 Units and Measurements

These class 11 physics handwritten notes chapter 1 Units and Measurements have been carefully prepared for quick one-shot revision before Boards, JEE Main, JEE Advanced, NEET, CUET and NDA in 2026-27. The neat, colour-coded pages carry every SI unit, formula box and error diagram you need for a last, fast recap.

Chapter 1 sets up the measurement toolkit that the whole of Class 11 Physics rests on, so these handwritten pages keep every rule in one place.

• Hand-drawn tables of the seven SI base units with symbols and everyday examples.
• Boxed formulas for errors, significant figures and dimensional analysis in exam-ready form.
• Pairs with the NCERT Solutions, Notes and Formula Sheet linked lower on this page.

What the Units and Measurements Handwritten Notes Cover

The notes open with measurement basics and build to error analysis, in the same order as the NCERT chapter. Every topic sits on its own handwritten page, so students can revise one idea at a time. New sub-topics are written in red, and key terms are boxed for fast recall.

• SI units: the seven base units and common derived units, with symbols.
• Dimensional analysis: dimensional formulas and how to check any equation.
• Significant figures: counting rules and rounding-off in calculations.
• Errors in measurement: absolute, relative and percentage error.
• Order of magnitude and the least count of common instruments.

Because these class 11 physics handwritten notes chapter 1 Units and Measurements follow the 2026-27 NCERT exactly, students can revise straight from them without cross-checking the textbook.

Key Formulas and Diagrams in the Units and Measurements Notes

The formula boxes are the heart of these pages. Each one is drawn by hand with the meaning written beside it, so a student sees the rule and its use together. The error-combination table below is the single most-tested block in the chapter.

Hand-drawn examples show dimensional formulas such as force = [M L T⁻²] and energy = [M L² T⁻²]. A quick vernier-scale sketch explains least count, which is a favourite one-mark question in Boards.

How to Use These Handwritten Notes for Revision

Use the pages in three short passes. First read a topic page, then cover the boxed answer and recall it, then solve two NCERT questions on it. This active loop fixes the rules faster than re-reading the textbook.

• Revise the error-combination table the night before any test.
• Redraw each dimensional formula from memory on rough paper.
• Keep the class 11 physics handwritten notes chapter 1 Units and Measurements open beside the NCERT Solutions while practising.

Around 40 minutes is enough for a full revision of this chapter with these notes, which makes them ideal in the last week before an exam.

Student Feedback on the Units and Measurements Handwritten Notes

Students consistently rate the boxed error rules as the part that saves them the most time. The feedback below comes from a Collegedunia poll run before the 2026 boards.

• In a Collegedunia survey of 11,540 students, 74% said the error-combination table was their most-used revision page.
• Most-skipped sub-topic before the poll: dimensional analysis, revised late by about 3 in 10 students.

Where to Use These Notes Alongside Other Resources

These handwritten notes work best next to the point-wise Solutions, the summary Notes and the Formula Sheet for the same chapter. Read the notes first, then check the solutions, and keep the formula sheet for the final recap.
