Measuring Mass
We will discuss about measuring mass. We know that, when we put two objects in a balance scale, the pan with heavier objects always drops downwards and the pan with lighter object goes up. So, we can compare weights of two different objects using a balance and say which is heavier.
We know the vegetable seller is weighing potatoes in kilogram. The goldsmith is weighing a ring in grams. The wheat bags are weighing in quintals.
Some of the following weights are used like 10 kg, 5 kg, 2
kg, 1 kg, 500 g, 200 g, 100 g, 50 g etc.
The unit of weight is the gram. Kilogram is a bigger unit of weight.
1 kilogram is equal to 1000 grams
or
1000 grams is equal to 1 kilogram
We write gram as 'g' and kilogram as 'kg' in short form.
1 kg is equal to 1000 g
or
1000 g is equal to 1 kg
Write the unit of
weight in which we will use to measure the following:
(i) eraser
(ii) biscuit packet
(iii) four toffees
(iv) your weight
(v) soap-bar
(vi) gold ring
(vii) bag of rice
(viii) your suitcase and bedding

We will discuss here about measuring the line segment i.e. how to draw and measure a line segment using scale or ruler. We can measure a line segment by two ways. (i) With the help of scale
We will learn measure a length using a ruler. The ruler given below has 15 cm marked on it. The length of the ruler is 15 cm. To measure a length of a pencil, place at the ‘0’ of the ruler at the one end of the pencil and note the position of the other end.
We will discuss here about the addition of hours, minutes and seconds. Let us consider some of the examples on adding time.
We know that hour, minute and second are the units, we use to measure the time. Now we will practice the questions given in the worksheet on conversion of time.
We normally use 12-hour clock system. The hour hand of the clock goes round the dial twice a day (24 hours). Some departments like railways, Airlines, etc use 24-hour clock system because they do
Units of time conversion chart are discussed here in hour, minute, second, day, week, month, and year. We know that there are 12 months in a year. The months of January, March, May, July, August, October and December have 31 days. The months of April, June, September and
We will discuss here about the conversion of minutes into hours. We know 60 minutes is equal to 1 hour, which is required to convert the measuring time from minutes to hours.
We will discuss here about the conversion of seconds into minutes. We know 1 second is equal to 1/60 minute, which is required to convert the measuring time from seconds to minutes.
We will discuss here about the conversion of hours into minutes. We know 1 hour is equal to 60 minutes which is required to convert the measuring time from hours to minutes.
There are different units of time. Second, minute, hour, day, week, month and year are the units of time. These have the following relations between each: 60 seconds = 1 minute
