1. Measurement

2. Metrology
Science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology
We measure many different dimensions, like length, mass, time, and temperature.
We use different units to measure different sizes of dimensions

3. Scientific Measurement
Two main systems
Many more
US Customary
Based on arbitrary measurements that have lasted through history
Conversions are hard to remember/calculate
Metric
Based on powers of ten
Prefixes determine magnitude of power of ten
