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.

Express the following in kilograms:
$190g$=$0.19kg$

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 by 1,000. A kilogram is one thousand grams.
So 190 grams = 190/1000 kilograms
190grams=0.19 kilograms.
So option A is the correct answer.

What is $873878\ mg$ into grams ?

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

  1. $873.878\ g$

  2. $87.3878\ g$

  3. $8738.78\ g$

  4. $87387.8\ g$

Show answer
Correct Option: A
Explanation:

$1\ \ g=1000\ \ mg$

$1 \ \ mg=\dfrac{1}{1000} \ \ g$
$\Rightarrow 1\ \ mg=.001\ \ g$

$873878\ \ mg=873878\times.001=873.878\ \ g$

So option $A$ is correct.

Convert $0.05$ kg into grams.

  2. $5\ g$

  3. $50\ g$

  4. $500\ g$

Show answer
Correct Option: C
Explanation:

$1\ \ kg=1000\ \ g$

$0.05\ \ kg =0.05\times1000=50\ \ g$
So option $B$ is correct.

What is $1000$ milligrams in kg ?

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

  1. $0.1$ kg

  2. $0.01$ kg

  3. $0.001$ kg

  4. $0.0001$ kg

Show answer
Correct Option: C
Explanation:

We know $1 $ g $=1000$ mg

$\Rightarrow 1 $ mg $=0.001 $ g
$\Rightarrow 1000$ mg $ =0.0001\times1000=1 $g
$1 $ kg $=1000 $ g
$\Rightarrow 1 $ g $=0.001 $ kg
Option C is correct.

Convert $0.04892$ kg into milligrams.

  4. $489200$ mg

Show answer
Correct Option: B
Explanation:

$1\ \ kg=1000\ \ grams$

$1\ \ gram =1000\ \ mg$
$\Rightarrow 1\ \ kg=100000\ \ mg$
$.04892\ \ kg=.04892\times100000=48920\ \ mg$
Option $B$ is correct.

$90000 \ \text{mg}=$ _____ $\text{kg}$.

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

  1. $0.9$

  2. $0.09$

  3. $9$

  4. $90$

Show answer
Correct Option: B
Explanation:

$1 \ \text{ g} =1000\  \text{mg}$

$\Rightarrow 1 \  \text{mg}=.001 \ \text{ g}$
$\Rightarrow 90000 \ \text{mg}  =.0001\times90000=90 \ \text{ g}$
$1 \ \text{kg}=1000 \ \text{ g}$
$\Rightarrow 1 \ \text{g}=.001 \ \text{ kg}$
$\Rightarrow 90 \ \text{g} =90\times.001=.09 \ \text{ kg}$
Option B is correct
