Technical Physics 1 Technical Measurement What do we measure? Fundamental properties mass (weight) k ilogram length m eter time s econd temperature Kelvin * electric charge (coulombs) and light intensity (candela) will be discussed later in this class Derived quantities density, velocity, force, etc. .. Systems of measurement Metric system vs English system Metric (SI) International system •standardized •international •consistent base units •multiples of 10 English (US) system •non-standard •only US •no consistent base units •no consistent multiples Using the Metric system Base units mass gram(g) length meter (m) liquid volume liter (l) time second (s) Prefixes for multiples of 10 T - - G - - M - -k h d (base) d c m - - μ - - n - -p move the decimal to convert Moving the decimal Converting measurements
