What to Focus On
- Measurement is a comparison with a standard scale.
- A result of measurement must always include both number and unit.
- A unit should be relevant, convenient, and well defined.
- Body-based units are not reliable for exact measurement.
- The standard cubit was an early attempt to create uniform measurement.
- India used different systems in ancient, medieval, and British periods.
- Standard units solve the problem of variation in body-based units.
- The metre has a current modern definition based on light.
- The Metre Convention was signed in 1875.
Common Mistakes to Avoid
Any number written with a unit is enough to describe a measurement.
Body-based units such as hand span, cubit, foot, and pace are good standard units because they are easy to use.
The metre has always had only one definition, so historical changes do not matter.
Memory Tips
Measurement means counting how many times a chosen scale is used
Value of a physical quantity = numerical quantity x unit
A unit must be relevant, convenient, and well defined
Body-based units are arbitrary and inaccurate
