Question

If $1\,tonnes = 1000\,kg$; then how much tonne is $32500\,kg$?
A. $32\,tonnes$
B. $32.5\,tonnes$
C. $325\,tonnes$
D. $3.250\,tonnes$

Answer 1

To solve this problem study about metric systems and units of different basic units in metric systems. Metric system is the system that is used in measuring basic physical quantity length, volume, distance, temperature, and weight. It relies on the three basic units through which anything in the world can be measured. Use basic math or unitary methods to convert the kg into tonnes.

Complete step by step answer:
We know that the Metric system uses three basic units through which any quantity can be measured. The basic units that are used in metric system are:
Metre($m$): It is used for measuring length.
Kilogram ($kg$): It is used for measuring mass.
Second($s$): It is used for measuring time.

Now, it is said that $1\,tonnes$ is equal to 1000kg. we have asked to find the value of $32500\,kg$ in tonnes. Now, if we apply unitary method the problem can be stated as follows
1000 kg is equal to 1 tonne.
1 kg of mass is equal to $\dfrac{1}{{1000}}\,tonnes$.
Then, 32500 kg is equal to $= 32500 \times \dfrac{1}{{1000}}\,tonnes$.
That is equal to, $32.5\,tonnes$.
Hence, 32500 kg is equal to $3.250\,tonnes$.

Hence, option B is the correct answer.

Note: To solve this type of problem learn basic mathematics – division, multiplication, addition and subtraction. Then use a simple unitary method to convert the mass into any other unit. We use the same method for conversion into any other unit.
While kg is the SI unit of mass, the tonne is used when large mass is measured for any problem. Since, it shortens the expression with just the expression of tonne. We do the same thing to shorten any unit.
