# Capacity measurement: Kilobyte, Megabyte and Gigabyte

## COMMON CAPACITY MEASUREMENT

Below are the common capacity measurements;

• Kilometer: This is a unit of measurement that is used to measure distance.

Example: The distance between Lagos and Kaduna is 906km. This is the same thing as

906 000metres.   1000 meter (m) = 1kilometre (km).

• Kilograms: This is a unit of measurement that is used to measure weights of objects.

Example: The weight of my brother is 7kg. This is the same as 7000grammes.

1000grams (gm) = 1kilogramme (kg).

• Kilobyte: This is a unit of measurement that is used to measure the size of data and information in computer storage.

Example: The size of the diskette is 1 474.56KB. This is the same thing as 1474.56 x 1024 bytes or   1024bytes or 1.44KB.

1024bytes = 1 Kilobyte (KB).

• Kilowatt: This is a unit of measurement that is used to measure the amount of electric of current consumed.

Example: The amount of electric current consumed by our electric cooker is 0.002kilowatts. This is the same thing as 0.002 x 1000 watts or 2watts. 1000watts = kilowatt (KW).

## DIFFERENCE BETWEEN A KILOBYTE, A MEGABYTE AND A GIGABYTE

A kilobyte is a unit of digital information consisting of approximately 1,000 bytes. A megabyte contains approximately 1,000,000 bytes, while a gigabyte contains approximately 1,000,000,000 bytes. Therefore, major difference among the three storage units have to do with their storage capacities. A gigabyte has the highest storage units; kilobyte has the least storage capacity.

EVALUATION:

1. Explain the following; (a) Kilobyte (b) Kilogram (c) Kilowatt and (d) Kilometer.
2. State the difference between Kilobyte, Megabyte and Gigabyte.

SUMMARY:

• Kilometer is a unit of measurement that is used to measure distance.
• Kilograms is a unit of measurement that is used to measure weights of objects.
• Kilobyte is a unit of measurement that is used to measure the size of data and information in computer storage.
• Kilowatt is a unit of measurement that is used to measure the amount of electric of current consumed.
• A kilobyte is a unit of digital information consisting of approximately 1,000 bytes. A megabyte contains approximately 1,000,000 bytes, while a gigabyte contains approximately 1,000,000,000 bytes. Therefore, major difference among the three storage units have to do with their storage capacities. A gigabyte has the highest storage units; kilobyte has the least storage capacity.

ASSIGNMENT:

1. Define Kilowatt, Kilogram and Kilometer?
2. Distinguish between kilogram, kilometer, kilobyte, and kilowatt.

CONCLUSSION: the students understand the common capacity measurement.

TEACHERâ€™S EVALUATION: the students understand the different capacity measurements and their units.
