Question

Convert $3.1$ kilogram in milligram?

Answer 1

Kilogram is the measuring unit of weight, and accordingly the higher and smaller units of weight are used to write the measured value of weight using these units. These units are interchangeable to each other, when moving from higher to lower you have to multiply with the specified number as in rule of conversion, and while moving from lower to higher you have to use division.

Formulae Used: $1\,kilogram = 1000\,grams$,$1gram = 100\,centigrams$,$1centigram = 10\,milligrams$

Complete step by step solution: For the given question conversion from kilogram to milligram is asked here we have to go with three processes let’s say one two and three in first process we convert kilogram to gram in the second we will convert gram to centigram and in the third process we will finally convert centigram to milligram:
First process we get:

$$1\,kilogram = 1000\,grams \\\ 3.1\,kilogram\, = 3.1 \times 1000\,grams \\\ 3.1\,kilogram = 3100\,grams \\\$$

Now for the second process we get:

$$1gram = 100\,centigrams \\\ 3100\,grams = 3100 \times 100\,centigrams \\\ 3100\,grams = 310000\,centigrams \\\$$

Now for the third process we get:

$$1centigram = 10\,milligrams \\\ 310000\,centigrams = 310000 \times 10\,milligrams \\\ 310000\,centigrams = 3100000\,milligrams \\\$$

Additional Information: Milligram is not the least small unit but one of the smallest units in measuring units; small units are used for measuring small weights only where kilogram and centigram can have decimal numbers.

Note: International standard for measuring weight is kilogram. We know in one kilogram there is 1000 grams and in one gram there is ten milligrams likewise we know for kilometer and meter, in the same way this weight unit also works like the length unit conversions. The conversions we make are either from low to or high to low units.
