| From: | To: |
The Weight Conversion Calculator converts between different units of weight/mass including kilograms, grams, pounds, ounces, and stone. It provides accurate conversions using standardized conversion factors.
The calculator uses the conversion formula:
Where:
Explanation: The calculator first converts the input weight to kilograms (the SI base unit for mass), then converts from kilograms to the target unit. This two-step process ensures accuracy for all conversions.
Details: Accurate weight conversions are essential in cooking, science, engineering, medicine, and international trade where different measurement systems are used.
Tips: Enter the weight value, select the original unit, then select the target unit. The calculator will display the converted value with the appropriate unit label.
Q1: What's the difference between mass and weight?
A: Mass is the amount of matter in an object (constant), while weight is the force exerted by gravity on that mass (varies by location). On Earth, we often use them interchangeably.
Q2: Why are there so many weight units?
A: Different cultures and applications developed their own systems. The metric system (kg, g) is now standard in science, while imperial units (lb, oz) remain common in some countries.
Q3: How accurate are the conversions?
A: The calculator uses standard conversion factors defined by international agreements, providing high accuracy for most practical purposes.
Q4: Can I convert between metric and imperial units?
A: Yes, the calculator handles conversions between all supported units regardless of system (e.g., kg to lb, oz to g).
Q5: What's the conversion factor between pounds and kilograms?
A: 1 pound = 0.453592 kilograms exactly. This is the international avoirdupois pound definition.
