Definition of milligram How much is a milligram? Things that weigh 1 mg Solved Examples Practice Problems Frequently Asked Questions
One day, Adina woke up and found herself in the kingdom of ants
From time to time, every day at mealtime, these things came, but always in the same quantity
Adina noticed an unusual unit of weight
Because ants were only tiny creatures, they weighed their food in milligrams (mg) before serving it
So let’s help him!
Definition of milligram
Milligram unit
The milligram (mg) is a unit of weight or mass in the International System of Units (SI)
The SI prefix of a milligram is “milli,” derived from the Latin word “mille,” meaning one thousandth
So 1 milligram is equal to one thousandth of a gram or 0001 gram
In other words, $1 gram = $1000 milligrams
Example milligram
In our daily life, we can find milligrams written on our medicines to describe their measure
Also, you can find the amount of ingredients used in making (say) a lotion or shampoo in milligrams or the nutritional information on food packaging
Milligrams and other units of mass or weight

Milligrams and prefixes SI
Let’s see some of them
“Deca” means ten times
So a decagram is 10 times a gram
“Hekto” means a hundred times
So a hectogram is 100 times a gram
“Kilo” means a thousand times
So a kilogram is 1000 times a gram
Milligram conversion
We can use milligram chart given below for milligram conversion
1 milligram in metric units
1 milligram to centigram
1 milligram to decigram
1 mg $= 1 \div (10 \times 10) $ dg $= 001 $ dg
1 mg $= 1 \div (10 \times 10 \times 10) $ g $ = 0001 $ g
1 milligram to decagram
1 milligram per hectogram
1 milligram per kilogram
1 mg $= 1 \div (10 \ times 10 \ times 10 \ times 10 \ times 10 \ times 10) $ kg $ = 0000001 $ kg
1 milligram in US customary units
1 milligram in grains
1 milligram to the ounce
1 milligram per pound
Therefore, 1 mg weighs 1 ml (milliliter)
Therefore, one milliliter of water weighs 1 mg
A carat is a common unit of measure used to weigh pearls and gemstones
Things weighing 1 mg
Here are some common objects that weigh 1 mg:
A grain of salt/sand
A worker ant found some bread crumbs weighing 300 mg, some sugar grains weighing 30 cg, and small pieces of cake weighing 4 dg
From the conversion chart, 30 cg $ = 30 \times 10 $ mg
Therefore, the total weight of food found by the worker ant
Therefore, the total weight of food found by the worker ant
From the conversion chart, 3 hg $ = 3 \ times 10 \ times 10 \ times 10 \ times 10 \ times 10 $ mg
00154 grains of salt
We know that 00154 grains = 1 mg…… (5)
4 Kohinoor weighs 1056 carats
Solution: We know that $1 carat = $200 mg
5 An ant carries 3 dg of bread crumbs
The ant decides to take the remaining breadcrumbs up the hill
What is the total weight of food that the ant carries on its hill?
From the conversion chart, 3 dg $ = 3 \ times 10 \ times 10 $ mg
So, the weight of the remaining bread $= 300 – $70 mg
$= 100$ mg2Arrange the following in ascending order: (1) 3 carat diamond (2) 02 g grain of sand (3) 5 ml water (4) 20 mg breadcrumbs$(3) \lt (4) \ lt ( 2) \lt (1)$$(1) \lt (2) \lt (3) \lt (4)$$(3) \lt (4) \lt (1) \lt (2)$ $( 2) \lt (3) \lt (1) \lt (4)$CorrectIncorrect The correct answer is: $(3) \lt (4) \lt (2) \lt (1)$One carat $ = $200 mg
So $3 carats = 3 \times $200 mg
So $3 carats = 3 \times $200 mg
02 g $ = 02 \ times 10 \ times 10 \ times 10 $ mg (from conversion chart)
In ascending order, $(3) \lt (4) \lt (2) \lt (1)$3Express 50,000 mg in dag05 dag5 dag50 dag500 dagE IncorrectThe correct answer is: 5 dagFrom the graph of conversion, 50,000 mg = $ 50,000 \div (10 \ times 10 \ times 10 \ times 10) $
Which is bigger – gram or milligram?
A gram is larger than a milligram
So 1 gram is 1000 times larger than a milligram
What does a milligram measure?
A milligram is a unit in the SI system used to express the mass of small objects
Is a milligram smaller than a microgram?
On the other hand, a milligram is 1/1000 of a gram
Therefore, a microgram is 1000 times smaller than a milligram
How many milligrams of water are in a teaspoon?
Why do we rarely use mg for weighing things in everyday life?
A milligram is a small unit of weight, just a fraction of the three smallest units of mass in the US customary system – grains, pounds and ounces
