  1. Standards of Measurement

  2. Standards A standard is an exactquantity used to compare measurements Inch Foot

  3. Units Measurements Must Include a Number and a Unit 150 ?????? Feet? Inches? Centimeters?

  4. SI Metric System The InternationalSystem of Units, (SI), is the current metric system used in most countries and in science.

  5. SI Prefixes Prefixes are used with the name of the base unit indicating what multiple of ten should be used with the unit Kilo Hecto Deca Deci nano centi milli micro

  6. Measuring Length The baseunit of measurement for length, in the SI Metric System is the meter. All of the other units for length are in multiples of 10.

  7. Kilometer Kilo = Thousand1 Kilometer (km) = 1,000 meters (m)

  8. Hectometer Hecto = Hundred1 Hectometer (hm) = 100 meters (m)

  9. Decameter Deca = Ten1 Decameter (Dm) = 10 meters (m) Dec means Ten as in Decade 50’s 60’s 70’s 80’s

  10. Meter Base Unit = 1 meter (m) Meter was based on one ten-millionth of the distance from the equator to the north pole

  11. Decimeter Deci = Tenth 10 decimeters (dm) = 1 meter (m) Dec means Ten as in Decade 1 Decimeter

  12. Centimeter Centi = Hundredth 100 centimeters (cm) = 1 meter (m) Cent means Hundred as in Century or 100 cents in 1 dollar

  13. Millimeter Milli = Thousandth 1,000 millimeters (mm) = 1 meter (m) Milli means Thousand as in Millennium

  14. Metric Table for Length

  15. Measuring Volume Volume is the amount of space that an object occupies How volume is measured depends upon if it is a solid or a liquid

  16. Volume of a Solid To measure the volume of a solid, You measure its length, width, and height and multiply the three numbers and their units together. 2cm X 2cm X 2cm 8cm 3

  17. Volume of a Liquid To measure the volume of a liquid, pour the liquid into a graduatedcylinder.

  18. Using a Graduated Cylinder Read the volume below the meniscus

  19. Measuring Volume by Water Displacement Archimedes Principle states that the volume of an object is equal to the volume of waterdisplaced when the objects is immersed in water

  20. Measuring Volume by Water Displacement 1. Determine initial volume 2. Add the Object 3. Determine final volume 4. Volume = final volume – initial volume Initial volume = 200 mL Final volume = 260 mL Volume = 260 mL – 200 mL = 60 mL

  21. Liter The baseunit for measuring the volume of liquids in the SI Metric System is the liter. Liter

  22. Metric Table for Volume The prefixes and their associated values are the same as they are for length.

  23. Measuring Mass Matter is anything that has mass and takes up space Mass is a measurement of the amount of matter in an object All matter is made up of atoms Solid Liquid Gas

  24. Metric Table for Mass The base unit of measurement for mass is the gram (g)

  25. Relationship There is a relationship between volume and mass in the metric system, in relation to water. 1 g of H2O = 1 mL of H2O 1 mL of H2O = 1 cm3 of H2O and 1 kg of H2O = 1 L of H2O 1 L of H2O = 10 cm3 of H2O mL and cm3are often used interchangeably

  26. Converting in the Metric System King Henry died by drinking chocolate milk

  27. King Henry died by drinking chocolate milk Kilo Hecto Deca Base Deci Centi milli Convert 7m to cm 7m Write the number and unit given 7. Decimal begins after number 7.00 Add zero’s according to number line 700. Move decimal point to proper place 700 cm Add the unit

  28. King Henry died by drinking chocolate milk Kilo Hecto Deca Base Deci Centi milli Convert 15m to mm 15m Write the number and unit given 15. Decimal begins after number 15.000 Add zero’s according to number line 15000. Move decimal point to proper place 15,000 mm Add the unit

  29. King Henry died by drinking chocolate milk Kilo Hecto Deca Base Deci Centi milli Convert 30,000 mm to m 30,000 mm Write the number and unit given 30000. Decimal begins after number 30.000 Move decimal point to proper place 30 Remove zero’s after decimal 30 m Add the unit

  30. King Henry died by drinking chocolate milk Kilo Hecto Deca Base Deci Centi milli Convert 40,000 mm to Dm 40,000 mm Write the number and unit given 40000. Decimal begins after number 4.0000 Move decimal point to proper place 4. Remove zero’s after decimal 4 Dm Add the unit

  31. King Henry died by drinking chocolate milk Kilo Hecto Deca Base Deci Centi milli Convert 6 cm to km 6 cm Write the number and unit given 6. Decimal begins after number 0.00006 Move decimal point and add zeros 0.00006 km Add unit 6 x10 Km Change to scientific notation - 5

  32. The End
