What is a kilogram?

The kilogram is the SI base unit of mass. People use it worldwide for body weight, food, shipments, and lab work. Because of this global standard, medical and scientific records usually store mass in kilograms.

What is a pound?

The pound belongs to the Imperial/US customary system. It remains common in the United States and appears in some UK contexts. Therefore, if your audience expects pounds, converting from kilograms keeps your data easy to read.

The exact constant (and smart rounding)

Precise constant: 1 kg = 2.20462262185 lb.
For everyday tasks, 2.20462 is accurate and simple.
Rounding tips: use 1–2 decimals for fitness or nutrition. However, keep more decimals when clinical or scientific rules require it.

Why accuracy matters

Small errors can snowball. For fitness, precise numbers keep progress honest. In healthcare, dosages and device settings often depend on mass; consequently, accuracy protects patients. In science, consistent units prevent reporting mistakes. Moreover, shipping and logistics often price by weight, so correct conversion avoids rework and fees. Even in cooking, tight conversions help when you scale recipes.
