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 conversion equation can be written as:

x kg * 2.20462 lbs/kg = y lbs

Step 3: Plug in the given weight in kg

In this case, the given weight is 90.3 kg. So, we substitute x = 90.3 kg into the equation:

90.3 kg * 2.20462 lbs/kg = y lbs

Step 4: Perform the calculation

Multiply 90.3 kg by 2.20462 lbs/kg:

90.3 kg * 2.20462 lbs/kg = 199.517386 lbs

Step 5: Round the result (if necessary)

Since weight is often rounded to the nearest decimal place, you can round the result to the desired precision. In this case, rounding to one decimal place gives:

199.5 lbs

Therefore, 90.3 kg is approximately equal to 199.5 lbs.
