Understanding Weight Units: Kilograms, Stones, and Pounds
Before we jump into the conversion process, let's clarify what each of these weight units represents:
-
Kilogram (kg): The kilogram is the base unit of mass in the International System of Units (SI). It's widely used across the world, especially in scientific contexts.
-

-
Pound (lb): The pound is another common unit of weight, primarily used in the United States and a few other countries. One pound is equal to 0.45359237 kilograms.
The Conversion Formula
To convert kilograms to stones and pounds, we can use the following formulas:
-
Convert Kilograms to Stones: [ \text{Stones} = \text{kg} \div 6.35029318 ]
-
Convert Kilograms to Pounds: [ \text{Pounds} = \text{kg} \times 2.2046226218 ]
Using these formulas, we can convert 87 kg into stones and pounds.

Using the formula: [ \text{Stones} = \frac{87 \text{ kg}}{6.35029318} \approx 13.68 \text{ stones} ]
Step 2: Extract Whole Stones and Convert the Remainder to Pounds
The whole stones in 13.68 stones is 13 stones.
To convert the decimal part (0.68 stones) back into pounds, we can multiply by 14 (since 1 stone = 14 pounds): [ 0.68 \text{ stones} \times 14 \text{ pounds} \approx 9.52 \text{ pounds} ]
So, we round to get 10 pounds.
