  1. Metrics The International System of Units - SI

  2. Commonly used units/symbols • What are the units used to measure • Mass • Distance • Volume • Time • Temperature • What are their symbols?

  3. Fahrenheit • Water freezes/thaws at 32° • Water vaporizes at 212° • “Absolute Zero” is -459°

  4. Celsius • Water freezes/thaws at 0° • Water vaporizes at 100° • “Absolute Zero” is -273°

  5. Kelvin • Water freezes/thaws at 273 • Water vaporizes at 373 • “Absolute Zero” is 0

  6. Temperature Conversions • To convert ˚C to ˚F : • ˚C x 9/5, + 32 = ˚F • To convert ˚F to ˚C : • ˚F – 32, x 5/9 = ˚C

  7. Common prefixes • What are the common prefixes we use in metrics?

  8. Metric Prefix Table

  9. Avoirdupois weight

  10. Is there an English unit for mass? • The slug. It is a mass that accelerates by 1 ft/s² when a force of one pound-force (lbf) is exerted on it. Therefore a slug has a mass of 32.17405 pound-mass or 14.5939 kg.

  11. Is there an SI unit for weight? • The Newton. It is equal to the amount of force required to give a mass of one kilogram an acceleration of one meter per second squared.

  12. Can you convert units? • KHD(U)DCM • King Henry Died while Drinking Chocolate Milk • Kilo x 1000 • Hecto x 100 • Deca x 10 • (unit) g, m, L • Deci x .1 • Centi x .01 • Milli x .001
