- Kilograms (kg): Metric standard, base unit here.
- Grams (g): 1 g = 0.001 kg.
- Milligrams (mg): 1 mg = 0.000001 kg.
- Carats (ct): Jewelry unit, 1 ct = 0.0002 kg.
- Micrograms (µg): 1 µg = 0.000000001 kg.
- Long Tons (UK): 1 ton = 1016.0469088 kg (2240 lb).
- Short Tons (US): 1 ton = 907.18474 kg (2000 lb).
- Short Hundredweights (US): 1 cwt = 45.359237 kg (100 lb).
- Long Hundredweights (UK): 1 cwt = 50.80234544 kg (112 lb).
- Troy Pounds: Precious metals, 1 lb = 0.3732417216 kg (12 Troy oz).
- Troy Ounces: 1 oz = 0.0311034768 kg.
- Pennyweights (dwt): 1 dwt = 0.00155517384 kg.
- Grains (gr): 1 gr = 0.00006479891 kg.
- Metric Tons: 1 ton = 1000 kg.
- Hundredweights (cwt): Typically UK, 1 cwt = 50.80234544 kg.
Building the Tool: Step-by-Step of Weight Conversion Calculator
- Core Functionality
- Base Unit: Kilograms for consistency.
- Conversions: Uses standard factors (e.g., 1 lb = 0.45359237 kg).
- HTML Structure
- A .calculator div with a logo, dropdown (select), input field, button, and scrollable result div.
- CSS: Aesthetic Appeal
- Background: Teal-to-blue gradient for a fresh, modern look.
- Glassmorphism: Semi-transparent calculator with shadow.
- Logo: “Weight” with a scale emoji (⚖️) for branding.
- Animations: Fade-in for the tool, slide-in for results.
- JavaScript: Logic
- Converts input to kilograms, then to all units.
- Validates for unit selection and non-negative numbers.
- Displays results with 3-decimal precision.
- Testing
- 1 kg → 2.205 lb, 35.274 oz, 0.001 metric tons, etc.
- 10 lb → 4.536 kg, 160.000 oz, 0.714 st.
- Edge Case: No input → “Please select a unit and enter a valid non-negative weight!”
Practical Applications
- Cooking: Convert pounds to grams for recipes.
- Shipping: Switch tons to kilograms for logistics.
- Jewelry: Translate carats to troy ounces.
- Science: Use micrograms for precise measurements.
