Express $49$ milligrams in centigrams.

maths length, mass and capacity problems on measurement choosing and converting between units conversion between different units

  1. $490$ centigrams

  2. $4900$ centigrams

  3. $0.049$ centigrams

  4. $4.9$ centigrams

Show answer
Correct Option: D
Explanation:

$1$ centigram is equal to $10$ milligrams.
Therefore, $49$ milligrams is equal to $\dfrac{1}{10} \times 49 = 4.9$ centigrams.

Convert the following into quintal:
$400\ $ ton

maths length, mass and capacity problems on measurement choosing and converting between units conversion between different units

  1. $400$ quintal

  2. $4,000$ quintal

  3. $40$ quintal

  4. $4$ quintal

Show answer
Correct Option: B
Explanation:

We know that


$1$  $ton =10$  $quintal$

$1$  $quintal =\dfrac1{10}$  $ton$

Given That, we have to convert $400$  $ton$  to   $quintals$

$400$  $tons =400 \times 10$  $quintals$

                   
                   $=4,000$  $quintals$

So, option $B$ is correct

Convert the following into kilograms :
$2.3$ ton

maths length, mass and capacity problems on measurement choosing and converting between units conversion between different units

  1. $23\ kg$

  2. $23,000\ kg$

  3. $230\ kg$

  4. $2,300\ kg$

Show answer
Correct Option: D
Explanation:

We know that


$1$  $ton =1000$  $kilograms$

$1$  $kg =\dfrac1{1000}$  $ton$

Given That, we have to convert $2.3$  $tons$  to   $kg$

$2.3$  $ton =2.3 \times 1000$  $kg$

                    $ = 2,300$  $kg$

So, option $D$ is correct

Convert the following into kilograms :
$400\ gm$ 

maths length, mass and capacity problems on measurement choosing and converting between units conversion between different units

  1. $0.4\ kg$

  2. $4\ kg$

  3. $40\ kg$

  4. $400\ kg$

Show answer
Correct Option: A
Explanation:

We know that


$1$  $kilogram =1000$  $gram$

$1$  $gm =\dfrac1{1000}$  $kg$

Given That, we have to convert $400$  $gm$  to   $kg$

$400$  $gm =\dfrac{1}{1000} \times 400$  $kg$

                    $ =\dfrac{400}{1000} $  $kg$

                   $=0.4$  $kg$

So, option $A$ is correct

Convert the following into tons :
$670$ quintal

maths length, mass and capacity problems on measurement choosing and converting between units conversion between different units

  1. $6700$ tons

  2. $670$ tons

  3. $67$ tons

  4. $6.7$ tons

Show answer
Correct Option: C
Explanation:

We know that


$1$  $ton =10$  $quintal$

$1$  $quintal =\dfrac1{10}$  $ton$

Given That, we have to convert $670$  $quintal$  to   $tons$

$670$  $quintals =\dfrac{1}{10} \times 670$  $tons$

                    $ =\dfrac{670}{10} $  $tons$

                   $=67$  $tons$

So, option $C$ is correct

Convert the following into grams :
$23\ kg\ 13\ g$

maths length, mass and capacity problems on measurement choosing and converting between units conversion between different units

  1. $23,130\ g$

  2. $2,313\ g$

  3. $23,013\ g$

  4. $213\ g$

Show answer
Correct Option: C
Explanation:

We know that


$1$  $kg =1000$  $gm$


Given That, we have to convert  $23$ $kg$  $13$  $gm$  to  $grams$


$23$ $kg = 23 \times 1000$  $grams$

               $= 23000$  $grams$

$23$ $kg$  $13$  $gm$ $ = 23kg + 13gm$

                   $ = 23000gm + 13gm$
                   $ = 23,013   $    $   gm$

So, Option $C$ is correct

On expressing the following in kilograms:
$247g$=$02.47kg$

maths length, mass and capacity problems on measurement choosing and converting between units conversion between different units

  1. True

  2. False

Show answer
Correct Option: B
Explanation:
To convert grams into kilograms we divide the given value by 1,000. A kilogram is one thousand grams.
247 grams= 247/1000 kilograms
247 grams= 0.247 kilograms
0.247≠2.47
So the given statement is false.
Option B is the correct answer

Express the following in kilograms:
$44kg$ $80gm$ = $44.08kg$

maths length, mass and capacity problems on measurement choosing and converting between units conversion between different units

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

To convert grams into kilograms we divide the given value by 1,000. A kilogram is one thousand grams.

80 grams= 80/1000 kilograms
So 80 grams = 0.08 kilograms.
44kg 80 grams = 44+0.080 kilograms
44kg 80 grams= 44.08 kilograms.
So option A is the correct answer.

Convert $2.387$ kg into grams.

  1. $2.387$ g

  2. $23.87$ g

  3. $238.7$ g

  4. $2387$ g

Show answer
Correct Option: D
Explanation:

$1\ \ kg=1000\ \ g\ 2.387\ \ kg=2.387\times 1000=2387\ \ g$

So option $D$ is correct
