9 What Is Measurement? 📏 | Easy Tricks, Units & 🎯 Fun Learning for Kids | ✨BrightCHAMPS Math

10 ▶

11 Measurement is defined to describe the comparison between an unknown quantity and a known quantity with standard units. It is one of the fundamental building blocks of<a>mathematics</a>that holds great importance, as it allows us to compare and calculate height, length, width, and numerous other physical quantities.

12 They are represented with certain units for example, meters, kilos, pounds, minutes, seconds, and many more.

13 ParentTip: Ask your child to guess their height without measuring? Now, measure it. This is called measurement.

14 <h2>History of Measurement</h2>

15 The earliest recorded sources of measurement goes back to Ancient Egypt.

16 In the early 3000 BCE, the Egyptians used measurement as a technique to build pyramids and other structures. They coined the<a>term</a>"cubit" (the length of the forearm). It was built out of a black granite rod, which they even used to measure ropes and rocks.

17 Later, in approximately 2500 BCE, the Babylonians developed the earliest unitary system for length and weight. After the Babylonians, around 500 BCE, the Romans created a system of measurement based on the distance covered on foot by the soldiers, which was also adapted by the Egyptians.

18 However, none of these were standard measurement units that were followed globally. The real evolution in the field of measurement came when France introduced the metric system in 1795.

19 The metric system, introduced by France, was widely adopted by many other European countries, marking a significant step forward in the evolution of standardized measurement.

20 The next step in the evolution of measurement and standardizing units for global acceptance occurred in 1960, when the SI system of units was introduced. Since then, there have been more developments that have enhanced the quality of measurement we experience today.

21 The developed version of SI unit is the metric system. Today, most of the countries follow SI except some countries like the US, Liberia, and Myanmar.

22 <h2>Measurement Units</h2>

23 Have you ever heard words like meters, liters, grams, feet, inches, pounds, etc.? These are called the units of measurement. They are used to referring to physical quantities such as length, weight, volume, etc.

24 These units are divided into standard units (SI) and non-standard units. Now let’s understand the differences between standard units and non-standard units.

25 Standard Units

26 Non-Standard Units

27 Universally accepted

28 Not universally accepted.

29 Consistent measuring units.

30 Measuring units may vary.Easy to convert from one unit to another.

31 They cannot be converted from one unit to another.

32 Examples: Meters, kilometers, seconds, kelvin, etc.

33 Examples: Hand span, arm span, cubit, foot span, pace, and finger width.

130 Tom wants to tile his garden, the length of each side of the square garden is 5200 mm. The cost of tiling 1 square meter of the garden is $2. How much is the total cost?

131 Okay, lets begin

132 The total cost for tiling the garden is $$54.08$.

133 <h3>Explanation</h3>

134 Given:

135 <ul><li>The length of the garden = $5200$ mm</li>

136 <li>Cost of tiles per square meter = $2</li>

137 <li>Length of the garden in meter = $5200 ÷ 1000 = 5.2 m$</li>

138 </ul>Area of the garden = $s^2 = (5.2)^2 = 27.04 m^2$

139 Total cost = $27.04 × 2 = $54.08$

141 <h3>Problem 2</h3>

142 Harry needs 5 kg of flour, but in the shop, they only sell flour in packets of 200 grams. Calculate how many packets of flour Harry needs to buy.

143 Okay, lets begin

144 The total number of flour packets that Harry needs to buy is 25.

145 <h3>Explanation</h3>

146 Given:

147 <ul><li>Total flour needed = 5 kg</li>

148 <li>The weight of flour in each packet = 200g</li>

149 </ul>Since, $1kg = 1000g$

150 Total flour Harry needs in grams $= 5 × 1000 = 5000 g$

151 Number of packets required $= 5000 ÷ 200 = 25$

152 Harry needs to buy 25 packets of flour.

157 The volume of the room is $7,480$ ft3.

158 <h3>Explanation</h3>

159 Given:

160 <ul><li>Volume of rectangular room $= L × W × H$</li>

161 <li>Here, $ L = 34 \space \text ft$</li>

162 <li>$W = 22 \space \text {ft}$</li>

163 <li>$H= 10 \space \text {ft}$</li>

164 </ul>Volume $= 34 × 22 × 10 = 7480 ft^3$

165 Therefore, the volume is 7480 ft3.

168 A boy’s height is 165 cm. Express the height in meters.

169 Okay, lets begin

170 1.65 meters.

171 <h3>Explanation</h3>

172 To convert the height from centimeters to meters, we divide it by 100 because 1 meter is 100 centimeters.

173 So, 165 centimeters in meters $= {165 \over {100}} = 1.65 \space \text {meters}$

179 <h3>Explanation</h3>

180 The formula for area of a square is side2

181 Therefore,

182 Side $= { \sqrt{area} }$

183 Side $= {\sqrt{64} }$

184 Side $= 8 \space m$

185 Now, the perimeter of the square $= 4 × side$
