If you are going to measure the mass of your dog, which of the following units should you use?
(i) Centigram(ii) Kilogram(iii) Gram(iv) Nanogram

Solution:

Option (ii) is the answer.

Mass is used to measure the weight of an object.

In the metric system of measurement, the most common units of mass are the gram and kilogram.

If a box that is 1 cm long on all sides is filled with water;

then the mass of water is 1 gram.

1gram = the mass of water in the box.

The units of mass in the metric system have the same prefixes as the units of length:

1 Kilogram (kg) = 1000 grams (g)

1 hectogram (hg) = 100 g

1 decagram (dag) = 10g

1 gram (g) = 1 g

1 decigram (dg) = 0.1 g

1 centigram (cg) = 0.01 g

1 milligram (mg) = 0.001 g

We can measure the weight of dog by using kilogram as the unit as remaining units are very small compared to kg.

If you are going to measure the mass of your dog, which of the following units should you use?
(i) Centigram(ii) Kilogram(iii) Gram(iv) Nanogram

Summary:

If you are going to measure the mass of your dog , kilograms should be used. 1 Kilogram (kg) = 1000 grams (g)
