Learn Class 4 Math - Length, Weight, Capacity, Time and Money

The Standard Unit of Measurement comes with Length, Weight, Capacity, Time, and Money. The metric system of it is agreed upon internationally and is considered a decimal measurement system.

  1. Capacity: In capacity, the overall amount an object can hold is further measured.
  2. Length and distance: Obviously, the length is termed as the measurement of an object, and distance is the measurement of between two places.
  3. Weight: When we talk of weight, it helps in measuring the heaviness of something.

Measuring Capacity

The two central units of measurement of Capacity are Liter and Milliliters. In other words, Liter is written as "I," and the millimeter is written as "ml."

Measuring Length

We understand that the standard unit of length is 'Meter,' inscribed in short as 'm'.

A meter length is split into 100 equal parts.

Each part is expressed in centimeters and written in short as 'cm.'

Therefore, 1 m = 100 cm & 100 cm = 1 m

The long distances are estimated in kilometers. This kilometer meets 1000 meters. The kilometer is signed in short as km.

1 kilometer (km) = 1000 meters (m) & 1000 m = 1 km

Measuring Weight

We know the central standard unit of mass or weight is kilogram that we write in short as 'kg.' The 1000th part of this kilogram is gram addressed in short as 'g.'

Therefore, 1000 gram = 1 kilogram & 1 kilogram = 1000 gram

Which means, 1000 g = 1 kg & 1 kg = 1000 g.

This gram (g) is a minimal unit of mass.
