Study Notes

Unit conversions: The process of changing a value from one unit to another.
Length units: Common units of length include:
- Meter (m)
- Centimeter (cm)
- Millimeter (mm)
- Kilometer (km)
- Inch (in)
- Foot (ft)
- Yard (yd)
- Mile (mi)
Conversion factors: Ratios used to convert between units, such as:
- 1 m = 100 cm
- 1 cm = 10 mm
- 1 km = 1000 m
- 1 in = 2.54 cm
- 1 ft = 12 in
- 1 yd = 3 ft
- 1 mi = 1760 yd

Measurement errors: Inaccuracies in measurement values due to various factors.
Types of errors:
- Systematic errors: Errors that occur consistently in the same direction, such as:
  - Instrumental errors (e.g., faulty instrument)
  - Human errors (e.g., misreading instrument)
- Random errors: Errors that occur randomly and unpredictably, such as:
  - Instrumental errors (e.g., electronic noise)
  - Human errors (e.g., accidental mistakes)
Error propagation: The process of calculating the total error of a measurement based on the errors of individual measurements.
Error types:
- Absolute error: The difference between the measured value and the true value.
- Relative error: The ratio of the absolute error to the true value.
- Percentage error: The relative error expressed as a percentage.
