Metric Measurement and Microscopy

How many centimeters are represented? 15 centimeters.

One centimeter equals how many millimeters? 10 millimeters.

According to Table 2.1, 1 um = 0.00***** mm and 1 nm = 0.001 um. Therefore, 1 mm = 1000 um = 1000 nm.

A mm = ***** *****, therefore 1.5 mm = 1.5 x 1000 = *****00 um.

A mm = 1000 um, therefore 0.25 ***** = 0.25 ***** 1000 = 250 um.

A nm = 0.001 um, therefore 55 nm = 55 x 0.001 = 0.055 um.

A cm = 10 mm, therefore 1.5 ***** = 1.5 ***** 10 = ***** mm = *****000 *****.

A nm = 0.001 um, therefore 5000 nm = 5000 x 0.001 = 5 um = 0.00***** mm = 0.0005 cm.

***** nm = 0.001 um, therefore ***** nm = 1000 x 0.001 = 1 um.

A um = 0.001 mm, therefore 1500 um = 1500 x 0.001 = 1.5 mm.

***** um = 1000 nm, ***** 7.5 um = 7.5 x 1000 = *****00 nm.

This circle is 35 mm = 35,000 um = 35,000,000 *****.

***** ***** centimeters are in a meter? 100 cm. How many milli*****s are ***** a meter? 1000 mm. The prefix milli means one thousandth.

***** example, if the b***** measures from the 22 cm mark to the 50 cm mark, then the length of the bone is 28 *****. If ***** bone measures from the ***** cm mark to midway between ***** 50 and 51 cm mark, its ***** is 285mm or 28.5 cm.

***** bone: 24 cm = 240 mm. Another bone: 22.5 cm = 225 mm.

***** g = 2000 mg; 0.2 g = 200 mg; and 2 mg = 0.002 g.

***** Procedure: Weight

3. ***** weight of the wooden block is 52.4 g = 52400 mg.

4. The item, a pencil, ***** 32 g = 32000 mg.

Vol*****e

***** liter = ***** ml.

Experimental Procedure: Volume

1. Length = 6 *****; Width = 3 cm; Depth = 2 cm.

Space occupied = 36 *****3. Therefore, the wooden block has a volume ***** 36 *****.

3. Fill the measuring cylinder ***** 50 ml, *****n fill the test tube with water from the test tube. The volume of the test tube is ***** minus ***** ***** remaining in the cylinder.

The test tube's total volume is 12 ml.

*****. Add the item to ***** cylinder and note the d*****ference in volume. The new volume minus the initial volume of 20 ml gives the volume of ***** object.

The item, an eraser, has a volume of 8 ml.

5. How could you determine how m*****ny drops from the pipette ***** ***** dropper bottle equal 1 ml? Count the ***** needed to fill the measuring ***** to 10 ml. Divide this number by 10 to give the number of drops in 1 ml.

***** many drops from ***** pipette of the ***** bottle ***** 1 *****? *****.

Are pipettes customarily used to measure large or small volumes?
