The Correct Answer and Explanation is:
90 kilograms is equal to approximately 198.42 pounds.
To understand this conversion, it is helpful to first recognize the two systems of measurement involved. The kilogram (kg) is the base unit of mass in the International System of Units (SI), commonly known as the metric system. This system is used by the vast majority of countries worldwide for scientific, commercial, and everyday purposes. In contrast, the pound (lb) is a unit of mass from the imperial and United States customary systems. It is primarily used in the United States, and to a lesser extent in a few other countries, for measuring body weight, food, and other common items.
The conversion between kilograms and pounds is based on a specific, internationally agreed upon standard. One kilogram is officially defined as being equal to approximately 2.20462262185 pounds. For most daily calculations, this number is often rounded to a more manageable figure, such as 2.205 or simply 2.2, depending on the level of precision required.
To convert 90 kilograms to pounds, you multiply the number of kilograms by this conversion factor. The calculation is as follows:
Pounds = 90 kg × 2.20462 lbs/kg
This results in 198.41598 pounds. For practical use, this value is typically rounded to one or two decimal places. Rounding to two decimal places gives you 198.42 pounds.
This type of conversion is frequently needed in various contexts. For example, an individual from the United States traveling internationally may need to convert their luggage weight from pounds to kilograms to meet airline requirements. Conversely, someone from a country using the metric system might need to convert their body weight to pounds when using fitness equipment or health charts designed for an American audience. Understanding this simple multiplication allows for an easy and accurate transition between these two common units of mass.
