Measurement is one of the units in the Grade 11 Physics content taught in PNG in both the PNG Standard Based school Curriculum & STEM curriculums and is basically assigning numerical values to quantities with defined units which may be used for comparison. The physical quantities measured can be used to describe its fundamental nature.

| Measurement Grade 11 Physics Unit |
Measurement introduces the student into effectively demonstrating the use of basic scientific instruments and analyse the readings to a reasonable degree of accuracy. This module provides students with an understanding of measurement including quantities, units and error analysis. Students can use this skill and knowledge to solve similar measurements related problems in other subjects and in the real world.
Measurement is Unit 1 on the five units in the Grade 11 physics subjects. In Grade 11, the units covered in PNG Secondary Schools and National High Schools are.
- 11.1 Measurement
- 11. 2. Motion (Kinematics)
- 11.3 Force and Motion
- 11.4 Work, Power and Energy
- 11.5 Electrical Principles
- 11.6 Electronics
