Metric Math

This guide introduces fundamental concepts of metric measurements including length (millimeters, centimeters, meters), volume (milliliters, deciliters, liters), and weight (micrograms, milligrams, grams, kilograms). It covers the relationships between units, such as 1000 millimeters equating to 1 meter, along with important terms like kilo (thousands), deci (tenths), centi (hundredths), and milli (thousandths). The guide also incorporates practical examples to enhance understanding, such as conversions and how to correctly read a ruler using metric units.

  1. Metric Math BMT Mr. Williams BSRT,RRT,RCP

  2. Metric Length • Millimeter • Centimeter • Meter • 1000 millimeters = 1 meter • 100 centimeters = 1 meter • 10 millimeters = 1 Centimeter

  3. Metric Volume (fluids) • Milliliter • Deciliter • Liter • 1 milliliter = 1 cubic centimeter • 10 deciliters = 1 liter • 1 liter = 1000 milliliters

  4. Metric Weight • Microgram • Milligram • Gram • Kilogram • 1000 microgram = 1 milligram • 1 gram = 1000 milligrams • 1 kilogram = 1000 grams

  5. Terms to know Gram measures mass or weight Liter measures volume or liquid Meter measures length or distance

  6. More Terms to know Kilo (K) = thousands Deci (d) = tenths Centi (c) = hundredths Milli (m) = thousandths

  7. Abbreviations Millimeter (mm) Centimeter (cm) Meter (m) Microgram (mcg) Milligram (mg) Gram (g) Kilogram (kg) Cubic Centimeter (cc) Milliliter (ml) Deciliter (dL) Liter (L)

  8. Review • What are the three measurements we are looking for with our metric math? • Length • Volume for fluids • weight

  9. Review If I have a measurement of 350m how many centimeters are there? If I have 2m how many millimeters do I have? If I have a weight of 4500mcg, how many milligrams do I have?

  10. Review 1ml = ______cc 20dL = _______L 2.4L = ________ ml

  11. How to read a ruler The ruler is divided up into 1/8 sections. The first line after the 1 is 1/8 the second line is ¼ the third line is 3/8, the fourth line is ½, the fifth line is 5/8 the sixth line is ¾, the seventh line is 7/8, and then finally the 1 inch mark.

  12. How to read a ruler What was wrong with what I just said?

  13. How to read a ruler We will use the top portion of the ruler. Notice all of the little lines are our millimeters and the larger lines are our centimeters. We are using metric measurements not standard.
