HouseholdMetric
Household:
Used in homeTeaspoon, tablespoon, pint,
quart, gallonPound, inch, foot, yardCan convert to metric by
simple math
Metric system:
Most widely used in health care
Decimal system; based on # 10
Monetary system in U.S. is based on metric
Metric system basic units:
Based on meter, gram & literMeter (m): lengthGram: (G), g, OR gm):
WeightLiter (l): liquid
GREEK AND LATIN PREFIXES:
Centi - 1/100 Milli - 1/1000
Kilo - x 1000
Metric System Uses:
MedicationsMeasure fluid intake Measure urinary outputMeasure newborn weight &
length
Common equivalents:
Distance:1 meter = 100 centimeters = 3.28 feet 2.54 cm = 1 inch
Weight:1 Kilogram (kg) = 1000 gram (g)= 2.2 pounds (lb)500 g = 1 lb
Volume:
1000 milliliters (ml) = 1 liter (l)
1 ml = 1 cubic centimeter (cc)
Memorize these Metric & household Equivalents:
1 liter = 1 quart30 ml = 1 ounce (2 tbsp)15 ml = 1 tablespoon5 ml = 1 teaspoon
1 kg = 2.2 pound1 ml = 15 drops1 inch = 2.5 cm
So….1 mm = meter1cm = meter1km = meter1ml = liter1L = liter1000ml = liter2000mg = grams1000mcg= grams
250ml = L0.5L = ml2G = mg500mg = G0.0300G = mg0.05mg = G1mcg = mg2kg = lbs60mg = G
0.005L = ml200ml = L0.0065G = G3.5cc = L4KG = G1ml = L0.05mg = G
Temp conversion you must remember:
F to C
F-32 x 5/9=C
Example: 98.6F98.6-32=
66.6
66.6 x 5 = 1 9
333 9
= 37C
C to FC x 9 / 5 + 32 = F
Example: 37C
37 x 9 =333
333 / 5=66.6
66.6 + 32 = 98.6
Practice:95F = C40C = F94F = C38C = F101F = C10C = F

I. The Scientific MethodA. An organized approach to learn how
the natural world works.
1. Ask a question
2. Form a hypothesis(a proposed explanation)
3. Perform an experiment
4. Analyze the data
5. Make your conclusion
II. The Importance of the Scientific MethodA. Continues to allow science to grow
B. Is testable by anyone else, and theoutcome should be the same.
