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 = y lbs

Step 3: Substitute the given value

In this case, the given weight is 78 kg. So, we can substitute x = 78 kg into the equation:

78 kg = y lbs

Step 4: Solve for y

To find the weight in lbs (y), we need to solve the equation. Multiply both sides of the equation by the conversion factor (2.20462):

78 kg * 2.20462 = y lbs

Step 5: Perform the calculation

Using a calculator or by hand, multiply 78 by 2.20462:

78 * 2.20462 = 171.96036

Step 6: Round the result

Since weight is typically rounded to the nearest whole number, round the result to the nearest pound:

171.96036 ≈ 172 lbs

Therefore, 78 kg is approximately equal to 172 lbs.
