Chapter 3: Units of Measurement The most important basic units for biologists are : meters (m) for length grams (g) for mass liters (L) for volume

Chapter 3: Units of Measurement

The most important basic units for biologists are : meters (m) for length grams (g) for mass liters (L) for volume

Chapter 3: Units of Measurement 100 centimeters (cm) = 1 meter meter stick 1,000 millimeters (mm) = 1 meter

Chapter 3: Units of Measurement The most important basic units for biologists are : meters (m) for length grams (g) for mass liters (L) for volume

Chapter 3: Units of Measurement mass of \$1 dollar bill is approximately 1 gram 1,000 milligrams (mg) = 1 gram 10 6 micrograms (µg) = 1 gram

Chapter 3: Units of Measurement The most important basic units for biologists are : meters (m) for length grams (g) for mass liters (L) for volume

Chapter 3: Units of Measurement 1 liter (1 L) 1 milliliter (1 mL) 1 microliter (1 µL)

Chapter 3: Units of Measurement 1 liter (1 L) 1000 milliliters (1000 mL) 10 6 microliters (10 6 µL) = =

Chapter 3: Units of Measurement Converting from one metric unit to another metric unit Convert both values to the same units, for example, meters: 1 cm = 1/100 meter = 0.01 meter 100 µm = 100 X 10 -6 meter = 1.0 x 10 -4 meter = 0.0001 meter Which is larger, 1 cm or 100 µm? larger
