Study Notes
- Measurement is crucial in math and science to quantify physical properties like size, weight, and volume.
- Units of measurement are pre-determined quantities used as references, standardized for consistency.
- The Metric System, also known as the International System of Units (S.I. Units), is widely used globally.
- The Metric System simplifies unit conversion with prefixes based on powers of 10, making calculations easier.
- For length, units like meters have prefixes like deci-, centi-, and milli-, each representing different magnitudes.
- Similarly, for mass, units like grams have prefixes like deci-, centi-, and milli-, following the same pattern of magnitudes.
- Conversion within the Metric System involves shifting decimal points to the right to increase units and to the left to decrease units, all based on powers of 10.
