Measurement is the process of comparing the quantity of the object to be measured with a standard unit of measurement. Length is the distance between any two points or places. A metre scale can be used for measuring the length and breadth of the science book. Mass is the amount of matter present in a body. With the help of a common balance, we can find the mass of our science book.

Match the following Column A Column B 1. Length of the forearm Metre 2. SI unit of length Second 3. Nano 10 3 4. SI Unit of time 10 - 9 5. Kilo Cubit

1. A cubit is an ancient unit of length. It is based on the length of the forearm from the elbow to the tip of the middle finger. 2. Metre is the SI unit of length. But we use kilometres as the unit for larger distances and millimetres and centimetres to measure smaller magnitudes of length. 3. The 'nano' is the prefix used to represent a very small unit of any physical quantity. A nanometre is equal to 10 - 9 m . 4. Second is the SI unit of time. Time is the duration between two events. A year is the time for the earth to rotate around the Sun. 5. Kilo usually used to denote 1000 . If metre or gram is considered to be the standards, when it is multiplied 1000 times, it is denoted as kilos. A Kilogram is 10 3 gm . Column A Column B 1. Length of the fore arm Cubit 2.
