presenting the new 1. How heavy is the person beside you? 2. 1 in = 2.54 cm
lesson 2. How tall are you? 3. 1 L = 2.11 pt
3. How much does your teacher’s water bottle contain? 4. 1 tsp = 5 ml
4. How much liquid multivitamin do you take daily? 5. 1 mi = 1.6 km
5. How long is your eyelashes?
B. Establishing a Do you like to measure things? Why? Answer each of the following questions using a metric
purpose for the What do you normally measure? system of measurement.
lesson What satisfaction do you get in knowing the correct 1. How long is your hair?
measurement of things? 2. How much water do
you drink every day?
3. How heavy is your
bag?
4. How long does it take
you to walk from your
house to the school?
5. How long do you
spend in doing your

centimeters. How will you convert your height in Smaller unit to a larger unit:
centimeters? divide by a power of 10.
Solution:
Another solution: Use proportion. Let x be the missing Illustrative example No. 1
quantity. Convert 4.2 dm to cm.
Using the conversion chart,
decimeter to centimeter is
one step to the right,
hence, multiply
by 101 or 10.

Illustrative example No. 4
Using proportion
Convert 4.12 kL to dL.
Using the conversion chart, kiloliter to deciliter is four
= steps to the right, hence, multiply by 104 or 10000.
= 4.12 kL(104 dL/ 1 kL)
