PRESENTED BY-SHEEBA TODD

the act or process of knowing the accurate length (how long), weight (how heavier) and capacity (amount of something).

Length

Measurements by body parts are rough measurements.

length

Let's see some examples-

Units of length-

Length is the size of an object from starting to end point.

units of measuring length.

Units of Length are:-

Millimeter

Centimeter

Decimeter

Meter

Kilometer

inch

Some rough measurements are:-

Measurement by Digit.

Rough measurements

Measurement by Pace.

Measurement by Handspan.

Measurement by cubit

FUN FACTS

Femtometre the shortest unit of length.

We can measure the distance of one to another by units of length.

FUN

FACTS

The equatorial circumference of Earth is 40,075 km.

We can measure distance between two cities or countries in metre(m) and kilometre(Km), using Google Maps.

Weight

Measuring weight means to measure the heaviness of a thing.

The amount of matter a thing consists of, is called its weight.

Weight

Units of measuring weight

Units of weight

The gram(g) and kilogram(Kg) are two units used to measure weight.

The heavier side of a weighing scale moves down.

Fun facts

fun facts -

In the U.S., we use inches, feet, cups, and ounces as form of measurement.

Since weight is the force of gravity pulling on an object, items weigh much less on the moon than they do on Earth.

If you weigh 80 pounds (36 kilograms) here on planet Earth, you will weigh closer to 13 pounds (six kilograms) on the moon.

CAPACITY

The units for capacity are litres (l) and millilitres (ml).

measuring units of capacity

fun facts

  • A milliliter is a very small amount of liquid.
  • It only fills the bottom of the teaspoon!
  • 20 drops of water make about 1 milliliter.

What is mass?

  • Mass is the measure of the amount of matter in an object.

  • Mass and Weight are different. Weight is the amount of gravitational force pulling on an object.

  • Weight can also change from place to place ,But mass always stays the same.
