Measuring Weight

Through the concept of weight measurement, we gain knowledge about the weight of different objects. Here students will learn the conversion of units of measurement.
In this learning concept, the students will also learn to

• Classify the weights and measure them.
• Evaluate the weight measurement units
• Identify the weight measurement chart.

Each concept is explained to class 4 math students using illustrations, examples, and mind maps. Students can assess their learning by solving the two printable worksheets given at the page’s end.

Weights and Measures:

To know how heavy or how light an object is, we need to measure the weight. We can tell the weight of something just by observation, but to know the exact weight, we need to measure it.

• To measure weights more precisely, we use standard units.
• Standard units are pre-defined and do not change person to person or object to object.
• To measure weight in standard unit, we use different tools such as balance, digital balance, beam balance, etc.
• Weights can be measured in different units. Some of the units are:
  • Kilogram (kg)
  • Gram (g)
  • Centigram (cg)
  • Milligram (mg)

 

Weight Measurement Units:

 

Conversion of Units of Measurement:

• To convert kilogram to Gram, we multiply it by 1000. To convert Gram to Kilogram, we divide it by 1000.
• To convert Gram to centigram, we multiply it by 100. To convert Centigram to Gram, we divide it by 100.
• To convert Centigram to Milligram, we multiply it by 10. To convert Milligram to Centigram, we divide it by 10.
  

 

Selection of appropriate measurement units:

• Weights of very light things should be measured in milligrams (mg).
• Weights heavier than 10 mg but lighter than a gram should be measured in centigrams.
• Weights heavier than one gram should be measured in grams.
• Very heavy objects should be weighed in kilograms.
