Estimates of Measurements in Grade V

Hello Friends, in day-to-day life we deal with many measurement issues like somebody ask us about our weight and height and if you don’t  know about measurement of height and weight, then you don’t have answer. So it is required to know how we estimate measurement. So, in  today's session we all are going to discuss about one of the most interesting topic of grade V mathematics of tamilnadu education board, Estimates of measurements which is quite similar to the topic analytical geometry problems. 
First of all we discuss what is measurement.
Measurement is the process which is used to determine physical quantity in length, time, temperature etc. to standard unit of measurement like  length in meter, time in second or temperature in degree Celsius,You can also get math help online about  this topic.
Now further we discuss how we measure units of measurements.
Here we discuss measurement of five major units

• measurement of length : Basically measurement of length is done in meter and we have to know all basic conversions about length like  kilometer to meter, meter to centimeter etc. So I will show you a chart which shows how length conversion is done (want to Learn more about Measurements ,click here),

     1 myriameter = 10 kilometer
     1 kilometer = 10 hectometer
     1 hectometer = 10 decameter
     1 decameter = 10 meter
     1 meter = 10 decimeter
     1 decimeter = 10 centimeter
     1 centimeter = 10 millimeter
     1 foot = 12 inches
     1 inch = 1000 mils
If you know all these conversions about length then you can easily measure physical quantity in length term.

• measurement of weight : We generally measure weight in kilogram, but if we want to measure weight in grams and pounds , we have to  know all conversions about weight. I will show you a chart which shows all conversions about weight

     1 metric ton = 1000 kilograms
     1 short ton = 2000 pounds
     1 stone = 14 pounds
     1 kilogram = 2.20 pounds
     1 pound = 16 ounces
     1 kilogram = 1000 grams
With the help of this chart, we can easily measure weight.

• measurement of volume: We can generally measure volume in liter and we can also measure volume in other units of liter. We have to know all  conversions about volume and following chart makes it easier to do these these things.

1 liter = 1.057 quarts

1 milliliter = .001 liter

1 cup = 236.6 milliliter

1 ounces = 29.57 milliliter

With the help of this chart, we can easily measure volume.

• measurement of time : Basically we measure time in seconds, but if we want to measure time in millisecond or microsecond, then we have to know all things about time conversion and following chart shows all conversions about time

1 day  = 24 hours 

1 hour = 60 minutes

1 minute = 60 seconds

1 millisecond = .001second

1 microsecond = .000001 second

This chart teaches us how we measure time.

• measurement of temperature : Basically we measure temperature in Kelvin, but if we want to measure temperature in Celsius or other unit of  temperature, then we have to know all things about temperature conversion and following chart shows us how we do conversions of  temperature by using formulas

To convert celsius to kelvin : k= 273+c

To convert celsius to farenheit : 9/5C = F-32

To convert Farenheit to rankins : R = F+459.5

To convert Rankins to Kelvin : 9k = 5R

This chart teaches us how we convert temperature from Kelvin to degree Celsius and degree Celsius to Fahrenheit etc.

This is all about measurement of units and in this session we almost cover full concept of grade V mathematics topic Estimates of measurements. I hope you learn and use concept in your real life and If you want to know about Collect/organize/graph data then you can refer Internet.
