Let’s start with the definition of Measurement

The idea of measurement is calculating a numerical value, that shows the size or amount of any physical quantity.

The collection of units of measurement is called the system of measurement. Metric System and US Standard Units are mainly used systems of measurement.
 

Metric System:

The metric system has three main systems of units. Meter for length, kg for mass, and seconds for time.

The following table lists some units of the Metric System.

 

Liquids

Mass

Length

Temperature

Milliliters (mL)

Grams (g)

Centimeters (cm)

Celsius degree celsius

Liters (L)

Kilograms (kg)

Meters (m)

 

 

Tonnes (t)

Kilometers (km)

 

 

US Standard Units:

The US Standard Units are mostly used in the United States. However, in the field of science and engineering, SI units are commonly used, which is derived from Metric Systems.

The following table shows some US Standard Units.

 

Liquids

Mass

Length

Temperature

Fluid Ounces (fl oz)

Ounces (oz)

Inches (in)

Fahrenheit Degree Fahrenheit

Pints (p)

Pounds (lb)

Feet (ft)

 

Quart (qt)

Tons (t)

Yards (yd)

 

Gallon (gal)

 

Miles (mi)

 

 

Some Common Conversion Factors:
 

Metric Units

US Standard Units

1 meter

3.281 feet, or 1.093 yards

1 kilogram

2.205 pounds

1 liter

1.057 quart, or 0.264 gallon

 

 

Practice Problems on Converting Standard Units of Measurement:

Question:1 Convert 10 meters in feet.

(a) 10.93 ft

(b) 30 ft

(c) 32.81 ft

(d) 393.72 ft

Correct Option: (c)

Explanation: The conversion factor is Explanation 1
 

Using the conversion factor, Explanation 1.1.

 Final answer: 10 meters is equal to 32.81 feet.
 

Question:2 Convert 50 pounds in kilograms.

(a) 110.25 kg

(b) 92 kg

(c) 25 kg

(d) 22.68 kg

Correct Option: (d)

Explanation: The conversion factor is Explanation 2

 

We could rewrite it as We could rewrite it as.

Final answer: 50 pounds is equal to 22.67 kilograms.
 

Question:3 Convert 56.78 liters in gallon. Round your answer to the nearest whole number. 

(a) 215 gal

(b) 15 gal

(c) 200 gal

(d) 6 gal

Correct Option: (b)
 

Explanation: The conversion factor is Explanation 3

Now, using the conversion factor:
 

 Explanation 3.1

Final answer: 56.78 liters would be approximately equal to 15 gallons.

 

Need Homework Help with Measurement Questions

 

Imagine your day-to-day routine and see how many times we use measurements in a day. You will be surprised to learn how our daily life is dependent on measurements. Everything around us can be pretty much measured. For Example, when you go to a store to buy a bag of oranges, then you look at the price of the bag something like $5 and the weight of the oranges as 2 lbs. Then when you proceed towards the billing desk and wait in the line, you measure the length of the line, the time it will take to reach the billing desk etc. Even driving back to your house, you calculate the temperature outside, the speed at which you need to drive on the road and so on. So, you see now, how everything pretty much around us is measurable. We can measure so many different things around us and most commonly we measure things by their length. their area, volume, capacity, and time it will take us to perform an activity.
 

Hence, different units of measurement are used for different things such as weight is measured in lbs or pounds whereas length is measured in centimeters, meters, inches etc. So it is very important to know how they are constructed, compared, and converted. 
 

There are two standard units of measurement. In, United States, we use U.S. Standard Units for measurement such as miles, pounds, and degrees Fahrenheit. The rest of the world uses the metric system for measuring things such as Kilometers, Kilograms, and degrees Celsius. The metric system was first proposed by the French astronomer /mathematician Gabriel Mouton in 1670 and later in 1790s it was standardized in Republican France.


Measurements as a topic are therefore very important for middle and high school students and can be considered as building blocks for solving with advanced math problems later in life.

Measurements Frequently Asked Questions:

Question1: What are measurements in math?
In math, measurement deals with the number that represents the size or amount of any quantity. For example, if we want to know our weight then the digit representing our weight comes after measurement, i.e.,55 kg denotes the weight of our body. Different types of measurement scale are used for measuring different quantities.

 

Q2. What are the basic measurements?
There are four basic measurement

  1. Mass or Weight
  2. Distance
  3. Area
  4. Volume

 

Q3. What are the 7 basic units of measurement?
International system of unit comprise of 7 basic unit of measurement:
 

  1. Metre for length,
  2. Kilogram for mass,
  3. Second for time,
  4. Ampere for electric current,
  5. Kelvin for temperature,
  6. Candela for luminous intensity and
  7. Mole for amount of substance.

 

Question4: What are the 5 types of measurements?
The 5 types of measurements are

  • Weight: For measuring the mass of an object. The units of measuring weight are gram, kilogram,tonnes or ounces and pound.


Example: Weight of 5 apples, we measure in grams or kilogram as 1kg or 1000gram.
 

  • Length: For measuring size i.e, how long or short the object is or a distance between two points.The units of measuring length are millimeter, centimeter, meter and kilometer.


Example : If we want to find the distance between our school and home, we measure the length in kilometers or meters. Assume,the distance between school and home is around 5km.
 

  • Capacity: For measuring the volume of any liquid we used capacity. The unit of measuring capacity is milliliter or liter.


Example: The quantity of milk we measured in a liter, i.e., 500ml
 

  • Time: Time may be described as a continuous and ongoing sequence of events that occur in order, from the past through the present to the future. The units of measuring time are seconds, minutes, hours,days,months, and year.
  • Temperature: It tells us how cold or hot an object is.The units of measuring temperature are degree celsius, degree fahrenheit,and kelvin. 

 

Question5: What is measurement error?
Measurement error is the difference between the observed value and the true value of the quantity.
Example, if we want to buy 1kg of apples but the shopkeeper weighs only 950gm and considers it as 1kg. Here we have a measurement error of (1000-950) 50gm.

 

Question 6: What does m stand for in measurement?
In the measurement ‘m’ stands for meter.One meter is equal to 100 centimeter and 1000 millimeter.

 

Question7: What is the unit of measurement?

  • Weight: The units of measuring weight are gram, kilogram,tonnes or ounces and pound.
  • Length: The units of measuring length are millimeter, centimeter, meter and kilometer.
  • Capacity: The unit of measuring capacity is milliliter or liter.
  • Time: The units of measuring time are seconds, minutes, hours,days,months, and year.
  • Temperature: The units of measuring time are seconds, minutes, hours,days,months, and year.
