MEASUREMENT OF WEIGHT

**Measurement of weight (or mass) -**

**We had earlier shown crayons on a balance to find the weight of objects. But the crayons may not be of the length, so the weights could be different each time we would use the balance.**

**So, to get the same weight every time an object is measured, we use fixed measures (standard units) like grams and kilograms to weigh objects and find out how heavy they are.**

**Grams –**

**We express the weight of light objects by using grams (g/gm)**

**1) A coin is about 50 gm**

**2) A box of chalks is about 100 gm**

**Kilograms –**

**We find the weight of heavy objects by using kilograms (Kg)**

**1 kilograms = 1000 gm**

**Example –**

**1) A small puppy’s weight is about 1 kg or 1000 gm**

**2) A newborn baby’s weight is about 3 kg or 3000 gm**

**When you visit a fruit or vegetable shop you will find the shopkeeper using weights made of metal. He uses weights of 5 kg, 2 kg, 1 kg, or so, to weigh fruits and vegetables in balance. When the pans balance, the weight on both the pans is the same.**

**Sometimes a single pan weighing machine is used to weigh objects. An arrow moves on a scale and we can read the weight of the object kept on the pan. Sometimes a weighing machine gives the weight directly on a monitor kept above the platform. Generally, heavy objects can be weighed on it.**
