Question

How do you convert $ 1.7kg $ to $ cg $ ?

Answer 1

Hint: Mass is defined as the resistance that a body offers to a change in its speed or position upon application of force. The greater the mass of an object the more force it requires to bring in similar changes in it compared to an object of lesser mass. Mass has the SI unit of Kilogram $ \left( {kg} \right) $.

Complete step by step solution:
We are provided with a mass of $ 1.7kg $ which needs to be converted to $ cg $ . For doing so we must know and understand the meaning of the prefix centi, It represents one hundred and when added with the word gram we get centigram or one by hundredth of a gram thus,
 $ 1g = 100cg $ .
Similarly, The word kilogram represents $ 1000g $ or,
 $ 1kg = 1000g $
Thus, $ 1kg = 1000g = 100000cg $
So, $ 1.7kg = 1.7 \times {10^5}cg $
Thus our required answer is $ 1.7 \times {10^5}cg $ .

Additional Information:
Generally, weight of an object and its mass are used interchangeably in normal conversations and this leads to development of a common confusion among the readers regarding what exactly differentiates these two terms. Mass of an object is an innate property that does not change with change in location it has a S.I. unit of Kilogram $ \left( {kg} \right) $ whereas when mass is multiplied with acceleration we get weight, the value of weight of the same object can be different at different locations depending on the acceleration provided, It has a S.I. unit of $ kg.m.{s^{ - 2}} $ and thus it can aptly be also defined as a force.

Note:
While doing such conversions always use your knowledge of normal unitary conversion and try to do the conversion in a stepwise manner I.e. do not go straight from $ kg $ to $ cg $ but rather go via $ g $ , this helps in reducing errors. Another point to be wary about is the simple mathematical operation, to master these types of questions and avoid any or all mistakes. Practice a lot on such questions.
