Conversion Definitions
Stone: A stone is a British unit of weight commonly used in the UK and Ireland, equal to 14 pounds or exactly 6.35029318 kilograms. It is traditionally used to measure body weight and is part of the imperial system. The stone unit simplifies weight expressions in certain regions.
Kilogram (kg): The kilogram is the base unit of mass in the International System of Units (SI). Defined as exactly 1,000 grams, it quantifies mass under the metric system. Kilograms are used worldwide for scientific, commercial, and everyday measurements of weight and mass.
Conversion FAQs
Why does the stone-to-kilogram conversion use the factor 6.35029318?
The factor 6.35029318 is derived from the exact definition that one stone equals 14 pounds, and one pound is defined as 0.45359237 kilograms. Multiplying 14 by 0.45359237 results in 6.35029318 kilograms. This value is fixed, so all stone-to-kilogram conversions use it.
Can I convert stone to kg without a calculator?
You can estimate by remembering 1 stone is about 6.35 kg. For rough calculation, multiply by 6.3 or 6.4; the result will be close, but not exact. For precise needs, a calculator or conversion table is recommended to avoid rounding errors.
What happens if a negative stone value is converted to kilograms?
Negative stone values convert to negative kilograms, which may represent weight differences, changes in mass, or theoretical values in physics. The conversion process is the same mathematically, but negative weights are rare in practical weight measurements.
Why is the conversion factor so precise?
The precision comes from international agreements on units of mass and force, to ensure consistency globally. The stone-to-pound and pound-to-kilogram relationships have exact definitions, so the conversion factor reflects that precision for accurate scientific and commercial use.
Is the stone unit used outside the UK and Ireland?
Stone is primarily used in the UK and Ireland for body weight. Other countries prefer kilograms or pounds. Its use outside these regions is rare and mostly seen in historical or cultural contexts rather than daily measurement.
