Measurements

Metric Measurement

In the BIO 137 lab, the metric system of measurement is used. It is important to be able to

convert from one metric unit to another.

We will be using 3 base units: gram (to measure mass)

meter (to measure distance)

liter (to measure volume)

Below is a table that gives you the base units in the center, larger units to the left of center, and

smaller units to the right of center.

To convert from a smaller unit to a larger unit, you simply need to move your decimal point

to the left the required number of places.

To convert from a larger unit to a smaller unit, you move your decimal point to the right the

required number of places.

46 mm = ____ m

To convert from mm to m, move your decimal point 3 places to the left (since the base unit is

three places to the left of milli- on the chart).

46 mm = .046 m

400 cg = ____ mg

To convert from cg to mg, move your decimal point 1 place to the right (since milli- is 1 place to

the right of centi- on the chart).

400 cg = 4,000 mg

1-2

Practice. Convert the following:

1. 25 mL = __________ dL 5. 3,500 mm = __________ m

2. 15 g = __________ mg 6. 0.005 km = __________ m

3. 750 g = __________ kg 7. 250 cL = __________ mL

4. 275 mm = __________cm 8. 6,750 cg = __________ kg

Scientific Notation

Scientists often deal with very small and very large numbers. This can be confusing due to

counting all those zeros! To simplify these numbers, we have learned to express them as powers

of 10.

Positive exponents indicate a number larger than zero.

Negative exponents indicate a number smaller than zero.

Convert 1,500,000 to scientific notation.

We move the decimal point so there is only ONE digit to its left (which is a total of 6 places to

the left in this example).

1,500,000 = 1.5 x 106

Convert 0.000025 to scientific notation.

We move the decimal point again so there is only ONE digit to its left (which is a total of 5

places to the right in this example).

0.000025 = 2.5 x 10-5

Practice. Convert the following to scientific notation.

1. 0.005 = ________________ 4. 500 = _________________

2. 5,050 = ________________ 5. 0.0025 = _______________

3. 0.0008 = _______________ 6. 0.25 = _________________

Practice. Convert the following to standard notation.

1. 1.5 x 103 = ___________ 4. 1.2 x 10

-4 = __________

2. 1.5 x 10-3

= ___________ 5. 1 x 104

= ____________

3. 3.75 x 102 = ___________ 6. 4 x 10

0 = ____________

Body Organization

Anatomical Position

In Human Anatomy & Physiology, we refer to the body parts in relation to a person standing in

the anatomical position.

Criteria:

Standing Erect

Facing Forward

Arms at Sides

Palms Forward

Feet Slightly Apart

1-4

Directional Terminology

When comparing the location of one body part to another, we use directional terms.

Know the following directional terms on Muscle Man:

A is Superior to B F & G are Ipsilateral (on the same side)

B is Inferior to A J & A are Contralateral (the opposite sides)

B is Anterior to D (on back side) G is Proximal to H

D is Posterior to C H is Distal to G

E is Medial to F (on side of leg) G is Intermediate to H & K

F is Lateral to E 1-5

Planes of Reference

Know the following planes of reference on a diagram or organ:

A Frontal plane divides the body or an organ into Anterior/Posterior halves.

A Median (Midsagittal) plane divides the body or an organ into equal Left/Right halves.

A Transverse plane divides the body or an organ into Superior/Inferior halves.
