Question

How can you change masses to kilograms? 2500grams is equal to?

Answer 1

Hint: Here we need to convert the given 2500 grams to kilograms. We know that \[1000{\text{ grams}} = 1{\text{ kilograms}}\] . In other words if we want to convert the given mass in grams to kilograms we simply divide that number by 1000.

Complete step by step solution:
Given, 2500 grams. That is
 \[ \Rightarrow {\text{2500g}}\] .
We know \[1000{\text{ grams}} = 1{\text{ kilograms}}\]
That is 1000 grams is equal to 1 kilogram. Then,
2500 grams is equal to
 \[ \Rightarrow \dfrac{{2500g \times 1kg}}{{1000g}}\]
 \[ \Rightarrow 2.5kg\] . This is the required answer.
That is 2500 grams is equal to 2.5 kilograms.
So, the correct answer is “2.5 kilograms”.

Note: If we want to convert 2.5 kilograms to grams all we need is to multiply that number by 1000.
We have \[ \Rightarrow 2.5kg\] .
Now we know that
1 kilogram is equal to 1000 grams. Then,
2.5 kilograms is equal to
 \[ \Rightarrow \dfrac{{2.5kg \times 1000g}}{{1kg}}\]
 \[ \Rightarrow 2500g\]
We represent grams by ‘g’ and kilograms by ‘kg’. The SI (international system) unit of mass is kilogram. The CGS (centimetre-gram-second system) unit of mass is gram. We should know that mass and weight are different. The quantity of matter within an object is known as mass whereas the force with which an object gets pulled towards earth is known as weight.
