What Are Pounds and Kilograms?
Before diving into the conversion process, it's important to understand what pounds and kilograms are and their place in measurement systems.
Pounds (lbs)
- Pounds are a unit of weight primarily used in the United States and a few other countries.
- The pound is part of the Imperial system, which is used mainly in the US customary units.
- One pound is traditionally defined as exactly 0.45359237 kilograms.
Kilograms (kg)
- Kilograms are the base unit of mass in the International System of Units (SI).
- They are widely used around the world for scientific, medical, and everyday measurements.
- One kilogram is defined as the mass of the International Prototype Kilogram, a platinum-iridium alloy cylinder stored in France.
Understanding these fundamental differences helps clarify why conversions are necessary and how they are performed.
The Conversion Process: 105 Pounds to Kilograms
Converting pounds to kilograms involves using a fixed conversion factor. The precise factor is:
