To convert kilograms (kg) to pounds (lbs), you can use the following step-by-step instructions:

Step 1: Understand the conversion factor

1 kilogram (kg) is equal to 2.20462 pounds (lbs). This means that to convert kg to lbs, you need to multiply the weight in kg by 2.20462.

Step 2: Set up the conversion equation

Let’s denote the weight in kg as “x” and the weight in lbs as “y”. The equation to convert kg to lbs is: y = x * 2.20462.

Step 3: Substitute the given value

In this case, the given weight is 2.1 kg. So, we substitute x = 2.1 into the equation: y = 2.1 * 2.20462.

Step 4: Perform the calculation

Multiply 2.1 by 2.20462:

y = 2.1 * 2.20462

y ≈ 4.62969

Step 5: Round the result (optional)

Since weight is typically rounded to a certain number of decimal places, you can round the result to your desired precision. In this case, let’s round to two decimal places:

y ≈ 4.63

Therefore, 2.1 kg is approximately equal to 4.63 lbs.
