Question

Convert the following quantity as indicated:
2500 kg= ________metric tonne

Answer 1

Hint: The units kg and metric tonne both are units of weight. Tonne is used to measure heavy objects like cars, trucks, etc. So, to solve this question, use the relationship between metric tonne and kg. First write how many kg are equal to1 metric tonne. 1000 kg is equal to one metric tonne. Use this relation to find how many metric tonnes are equal to 2500 kg.

Complete answer:
We know,
1 metric tonne= 1000 kg. ..(1)
So, let x metric tonne be equal to 2500 kg.
x metric tonne= 2500 kg. ..(2)
Now, cross-multiplying the equation. (1) and equation. (2) we get,
$2500 \times 1= x \times 1000$
$\Rightarrow x= \dfrac {2500}{1000}$
$\therefore x = 2.5$
Thus, 2.5 metric tonne is equal to 2500 kg.
Hence, 2500 kg= 2.5 metric tonne.

Additional Information:
The fundamental unit of mass is kg. But when we deal with physical quantities, there is a large variation in the magnitudes like nanograms, milligrams, etc. Thus, to deal with such large numbers other units were brought into consideration. The other units include pound, metric tonne, etc. The terms like nano, milli, deci, etc are the generic terms which are used in measurement of length also.

Note:
To answer these types of questions, students must know how to convert one unit to another. They should not get confused between ton and metric tonne. Both are units of measurement but are not the same. 1 ton is approximately equal to 907 kg whereas one metric tonne is equal to 1000 kg. Metric tonne is denoted by t. It is a measurement unit which is used worldwide.
