The Correct Answer and Explanation is:
Based on the image provided, the question is a unit conversion problem.
Answer: 140 kilograms is equal to approximately 308.65 pounds.
Explanation
Converting kilograms to pounds involves switching between the metric system and the imperial or U.S. customary system of measurement. The kilogram (kg) is the base unit of mass in the International System of Units (SI), which is used by the vast majority of countries for scientific and everyday purposes. The pound (lbs), on the other hand, is a unit of mass primarily used in the United States, the United Kingdom, and a few other nations. The abbreviation “lbs” comes from the Latin word libra, which was an ancient Roman unit of weight.
The most important piece of information for this conversion is the specific relationship between these two units. One kilogram is equivalent to approximately 2.20462262 pounds. For most daily applications, this value is often rounded to 2.205 or even just 2.2 for quick estimations.
To perform the calculation for converting 140 kilograms to pounds, you multiply the mass in kilograms by the conversion factor. Using the more precise value will yield a more accurate result.
The calculation is as follows:
140 kg × 2.20462 lbs/kg = 308.64712 lbs
For practical purposes, it is standard to round the result to a reasonable number of decimal places. Rounding to two decimal places gives us 308.65 pounds. This level of precision is suitable for most contexts, such as measuring body weight, shipping weights, or ingredients.
If you were to use the simpler, more common approximation of 2.2, the calculation would look like this:
140 kg × 2.2 lbs/kg = 308 lbs
While this simplified calculation is very close to the precise answer and excellent for mental math, the more accurate figure of 308.65 pounds is preferred when precision matters. This conversion highlights that a kilogram is a larger unit of mass than a pound, which is why the numerical value increases when converting from kilograms to pounds.
