Question

How many grams are there in two dekagrams?

Answer 1

Firstly, we should analyse which one of the two units is the smaller unit. The smaller unit among dekagram and gram are obviously gram. To convert from a smaller unit to a bigger unit we divide the number by ten.

Complete step-by-step answer: Gram is denoted with a symbol $'g'$ and the decagram is denoted with $'dag'$ . When you are changing from grams to decagrams, that means you are requesting to change over one gram to one $dag$ .
Gram is defined as the metric system of unit of mass. $1$ gram is equal to the $\dfrac{1}{1000}$ kilogram
Dekagram is defined as the metric system of unit of mass. $1$ dekagram is equal to the $10$ grams.
The $'da'$ in the abbreviation in $'dag'$ means ten and $'g'$ means grams.
In this question, as we know that $1\,dag=10\,g$
To get the value of $2\,dag$ in grams, we multiply two with $10\,g$ , that is equal to $20\,g$
$1\,dag=10\,g$
$\Rightarrow 2\,dag=10\times 2$
$\Rightarrow 2\,dag=20\,g$
Additional information:
Measurement is very important for calculation. Without any measure technique, scientists will not be able to do their experiments. It is a technique in which the properties of object are calculated by comparing them to a standard.
Scientists use a metric system to calculate the properties of objects.
Let us see the base units of measurements:
Length – meter
Time – second
Current – Ampere
Mass – kilogram
Temperature – Kelvin
Amount of substance – mole
Luminous intensity – candela
Dekagram and grams lie in the measurement unit of mass.

Note: If we are converting one dekagram to grams, then we will multiply with $10$ because we are converting from bigger unit to smaller unit and if we are converting one gram to dekagram, then we will divide by $10$ because we are converting from smaller unit to bigger unit.
Here, dekagram is a bigger unit and gram is a smaller unit.
