Different Systems of Measurement

Introduction :

In this we will see about different systems of measurement. Measurement is one of the most important tools in math. Without measurement we cannot measure any of our resultant data. Measurements are classified as many types. They are inches, meter, centimeters, kilograms, grams, miles, liters, pounds, and so on. Let us study about different systems of measurement.
Example Problems for Different Systems of Measurement:

Example problem 1: Add the followings: 3 T 1,088 lb + 4 T 241 lb

Solution:

We know that,

1 ton (T) = 2,000 pounds (lb)

Add the measurements. Add tons to tons and pounds to pounds.

3 T 1,088 lb + 4 T 241 lb = 7 T 1,329 lb

Answer: 3 T 1,088 lb + 4 T 241 lb = 7 T 1,329 lb

Example problem 2: At 1:00 AM, the temperature started dropping 2 degrees Celsius per hour until it reached -14 degrees Celsius at 4:00 AM. What was the temperature at 1:00 AM?

Solution:

Work backwards. The temperature dropped 2 degrees Celsius for 3 hours, so add 3 times:

-14°C + 2°C + 2°C + 2°C = -8°C

Therefore, the temperature was -8 degrees Celsius.

Answer: The temperature was -8 degrees Celsius.
Practice Problems for Different Systems of Measurement:

Practice problem 1: How many degrees Celsius (°C) is 113°F?

Practice problem 2: At 5:00 AM the temperature was 50°F, at 9:00 PM the temperature was 45°F, and at 10:00 PM the temperature was 43°F. When was it coolest?

Practice problem 3: Multiply: 28 feet 2 inches times 2

Practice problem 4: Convert: 1/3 of a yard into feet.

Solutions for different systems of measurement:

Solution 1: 113°F = 45°C

Solution 2: 43 is the smallest of the three numbers, so 43°F is the coolest. So, it was coolest at 10:00 PM.

Solution 3: 28 feet 2 inches times 2 = 56 feet 4 inches

Solution 4: 1 feet
