This comprehensive guide will walk you through the process step by step, ensuring you have a clear understanding of the conversion.
Understanding the Conversion
Before we dive into the conversion process, let's grasp the basics. The pound (lbs) and kilogram (kg) are units used to measure weight or mass. While pounds are commonly used in the United States and a few other countries, kilograms are the standard unit for weight in the International System of Units (SI) and are widely used globally.
To convert between these two units, we'll use a simple formula: 1 kg = 2.20462 lbs. This means that one kilogram is approximately equal to 2.20462 pounds. By applying this formula, we can easily convert 140 lbs to kg.
Step-by-Step Conversion Process
-
Start by writing down the given weight in pounds: 140 lbs.
-
Next, we'll use the conversion formula. Since we want to convert pounds to kilograms, we'll use the reciprocal of the formula: 1 lbs = 0.453592 kg.
-
Multiply the given weight by the conversion factor: 140 lbs * 0.453592 kg/lbs = 63.49688 kg.
-
Round off the result to the desired precision. In this case, we can round it to two decimal places: 63.50 kg.
So, 140 lbs is approximately equal to 63.50 kg! That's a simple and accurate way to convert weight from pounds to kilograms.
