Metric system is a decimalized system of measurement. It exists in several variations with different choices of base units. Metric units are widely used around the world for personal, commercial and scientific purposes. ● Millimeter ● Centimeter ● Decimeter ● Meter ● Kilometer

Common English units and each equivalent ● 1 foot (ft) = 12 inches (in) ● 1 yard (yd) = 3 feet ● 1 yard = 36 inches

Common Metric units and each equivalent ● 10 millimeters (mm) = 1 centimeter (cm) ● 10 centimeters = 1 decimeter (dm) ● 10 decimeters = 1 meter (m) ● 100 centimeters = 1 meter

Some of the English to metric equivalents ● 1 inch = 2 centimeters ● 1 foot = 30 centimeters ● 1 yard = 91 centimeters

I. Converting the unit of linear measurement from English to English Measurements

Examples: 1.) 10 feet = _________ inches

Steps in solving the above problem: Step 1: Remember that 1 foot is equal to 12 inches, thus: 10 ft x 12 in 1 ft Step 2: Multiply 10 feet to 12 inches, thus:

How many inches are there in 10 feet?

10 ft x 12 in 1 ft Step 3: Cancel the common units of measurement, then perform the indicated operation, thus: 10 ft x 12 in = 120 in 1 ft

Therefore 10 feet = 120 inches 2.) 6 feet = _________ yard

Steps in solving the above problem: Step 1: Remember that 1 yd is equal to 3 feet, thus: 6 ft x 1 yd 3 ft Step 2: Multiply the numerator (6 ft) to (1 yd), and divide by the denominator (3 ft) thus: 6 ft x 1 yd 3 ft Step 3: Cancel the common units of measurement, then perform the indicated operation, thus: 6 ft x 1 yd= 2 yd 3 ft Therefore 6 feet = 2 yards

II. Converting the unit of linear measurement from Metric to Metric Measurements Examples: 1.) 100 millimeters = _________ centimeters

Steps in solving the above problem:

Step 1: Remember that 10 millimeters is equal to 1 centimeter, thus: 100 mm x 1 cm 10 mm Step 2: Multiply the numerator (100 mm) to (1 cm), and divide by the denominator (10 mm) thus: 100 mm x 1 cm 10 mm 7

How many centimeter are there in 100 millimeter?

III. Converting the unit of linear measurement from English to metric and vice versa Example: 1.) 10 inches = _________ centimeters Steps in solving the above problem:

Step 1: Remember that 1 inch is equal to 2 centimeters, thus:

10 in x 2 cm 1 in Step 2: Multiply the numerator (10 in) to (2 cm), thus: 10 in x 2 cm 1 in

Step 3: Cancel the common units of measurement, then perform the indicated operation, thus:

10 in x 2 cm = 25 cm 1 in

Therefore 10 inches = 25 centimeters 2.) 50 centimeters = ________ feet

Steps in solving the above problem:

Step 1: Remember that 1 foot is equal to 30 centimeters, thus: 50 cm x 1ft__ 30 cm Step 2: Multiply the numerator (50 cm) to (1 ft), and divide by the denominator (30 cm) thus: 50 cm x 1 ft 30 cm Step 3: Cancel the common units of measurement, then perform the indicated operation, thus:

50 cm x 1 ft = 1 ft 30 cm Therefore 50 centimeters = 1 feet 9

How many centimeter/s are there in 10 inches?

How many feet are there in 50 centimeters?

Reading a Ruler A ruler has two sides. One side contains an English System and the other side is the Metric System.

The Inch Graduation

The inch is divided into 16 graduations/lines. The first graduation is 1/16, the second graduation is 1/8 or 2/16, the third graduation is 3/16, the fourth graduation is 1/4 or 4/16 and so on.

Note: 1 inch is equal to 16 lines/graduations

The Centimeter Graduation

A Centimeter is divided into 10 graduations/lines. The first graduation is 1 millimeter (mm), the second graduation is 2 millimeters, the third graduation is 3 millimeters and so on.

Note: 1 graduation is equal to 1 millimeter (mm)

Therefore, we have 20 volts as the answer. We use Volts as the unit because we are ask for the voltage.

Sample problem 2. A kitchen appliance has a 220 volts supply from the outlet with a current flowing at 2 amperes. Determine its resistance. Solution: Using the formula R = V/I since we are ask the value of resistance. Thus:

R=V/I R= 220/ Dividing 220 by 2 will get a result of 110 Therefore, the value of our resistance is 110 Ohms (Ω)

Sample problem 3.

A cellphone charger has a 10 volts output voltage at 20 ohms resistance. Calculate its rated current. Solution: Since the current (I) has the unknown value in the problem, we will use the formula I = V/R. Thus:

I= V/R I = 10/ Dividing 10 by 20 will get 0. Therefore, we have 0 ampere (A) as the answer.

MULTITESTER

The multitester or multimeteris sometimes called the VOM (voltmeter,ohmmeter, milliammeter). It is the best instrument that can measure voltage,resistance and current. It is generally made of two types: the analog and the digital.
