The document provides information about measurement tools and systems of measurement. It defines various drawing and measuring tools like a compass, triangle, T-square, protractor, ruler, tape measure, scale, and divider. It also explains the metric and English systems of measurement, including linear equivalents and conversion tables between the two systems. Examples are given to demonstrate how to convert between millimeters, centimeters, meters, inches, feet, and yards.

4. Directions: Look for the name of the
drawing/measuring tools that you included in your
inventory before. There are eight (8) drawing/
measuring tools, look for at least six (6) tools to pass
the activity.

6. Compass-used for inscribing circles or arcs.
Triangle- used for drawing vertical and oblique lines
T-Square- used as guide in drawing horizontal lines
Protractor- it is a measuring tool used
for measuring and setting of angles
Ruler- the most popular type of measuring
tools, usually 6 to 12 inches in length
Tape Measure-used to measure length, used to measure
many of the distances that are too long for a ruler to
measure easily
Scale- main purpose is to
reproduce or enlarge the
dimension of size on a
drawing
Divider- is used for dividing distances into equal parts

19.  Measuring accurately is a skill that should be
developed. Inaccurate measurement would
mean waste of time, effort and materials. The
development of the skill in measuring starts
with the ability to read measurement.
INTRODUCTION

20. CARRY OUT MENSURATION AND CALCULATION
Two Systems of Measurement
There are two systems of measurement: the
English system which originated in
England and the Metric system or Systems
International (S.I) which originated in France.

21. CONVERSION OF FRACTION AND DECIMAL
The basic unit in the Systems International
measurement is called the meter. The
meter is divided into 100 centimeters. Each
centimeter is divided into 10 millimeters.

22. In the English system, the inch is divided into 16
graduations and the smallest graduation is read 1/16.

24. In the Systems International measurement OR Metric
System, the meter is divided into 10 millimeters

26. Metric system measurement (linear equivalent)
10 millimeters (mm.) = 1 centimeter (cm.)
10 centimeters (cm.) = 1 decimeter (dm.)
10 decimeter (dm.) = 1 meter (m.)
10 meters (m.) = 1 decameter (Dm.)
10 decameter (Dm.) = 1 hectometer (Hm.)
10 hectometer (Hm.) = 1 kilometer (Km.)

27. English System of Measurement (linear
equivalent)
12 inches (in.) = 1 foot (ft.)
3 feet (ft.) = 1 yard (yd.)

28. Metric Conversion Table
1 millimeter = 0.03937 inches (in.)
1 centimeter = 0.3937 inches (in.)
1 meter = 39.37 inches (in.)

29. Examples:
Convert the following into inches using metric
conversion table
130 mm = ________ inches
13 x 0.03937 = 5.1181

30. Examples:
5 cm = __________ inches
5 x 0.3937 = 1. 9685

31. Examples:
3 m = ___________ inches
3 x 39.37 = 118.11

32. English Conversion Table
1 inch (in.) = 25.4 mm. = 2.54 cm. = .0254 (m.)
1 foot (ft.) = 304.8 mm. = 30.48 cm = .3048 (m.)
1 yard (yd.) = 914.4 mm = 91.4 cm = .9144 (m.)

33. Examples:
Convert the following using English conversion table.
5 yards = ________ cm
5 x 91.4 = 457 cm

34. Examples:
Convert the following using English conversion table.
60 inches = ________ m
60 x .0254 = 1.524

35. Examples:
Convert the following using English conversion table.
2 feet = _________ mm
2 x 304.8 = 609.6

36. Directions: : Group the students into 5. Using a
ruler let them measure the given objects using
English System and convert it into Metric
System. (in - cm.)

47. Metric System Measurement (linear equivalent)
10 millimeters (mm.) = 1 centimeter (cm.)
10 centimeters (cm.) = 1 decimeter (dm.)
10 decimeter (dm.) = 1 meter (m.)
10 meters (m.) = 1 decameter (Dm.)
10 decameter (Dm.) = 1 hectometer (Hm.)
10 hectometer (Hm.) = 1 kilometer (Km.)
English System of Measurement (linear equivalent)
12 inches (in.) = 1 foot (ft.)
3 feet (ft.) = 1 yard (yd.)

48. English Conversion Table
1 inch (in.) = 25.4 mm. = 2.54 cm. = .0254 (m.)
1 foot (ft.) = 304.8 mm. = 30.48 cm = .3048 (m.)
1 yard (yd.) = 914.4 mm = 91.4 cm = .9144 (m.)
Metric Conversion Table
1 millimeter = 0.03937 inches (in.)
