Conversion Logic and Formula Explanation
This calculator uses a base unit conversion system. All values are first converted into a standard base unit and then converted into the target unit.
Step 1: Convert to Base Unit
Each category has a base unit:
- Length → Meter (m)
- Weight → Gram (g)
- Volume → Liter (L)
Conversion examples to base unit:
- Kilometer → Meter:
1 km = 1000 m - Centimeter → Meter:
1 cm = 0.01 m - Millimeter → Meter:
1 mm = 0.001 m - Kilogram → Gram:
1 kg = 1000 g - Pound → Gram:
1 lb = 453.592 g - Ounce → Gram:
1 oz = 28.3495 g - Milliliter → Liter:
1 mL = 0.001 L
Step 2: Convert Base Unit to Target Unit
Once the value is in the base unit, it is converted to the desired unit.
For example:
- Meter → Kilometer: divide by 1000
- Meter → Centimeter: multiply by 100
- Gram → Kilogram: divide by 1000
- Gram → Pound: divide by 453.592
- Liter → Milliliter: multiply by 1000
Example Conversion
Let’s understand with a real example:
Example 1: Convert 2 Kilometers to Meters
- Step 1: Convert to base unit
2 km × 1000 = 2000 meters - Step 2: Target unit is meters
Final result = 2000 meters
Example 2: Convert 500 Grams to Pounds
- Step 1: Base unit (gram stays same)
500 g - Step 2: Convert to pounds
500 ÷ 453.592 = 1.1023 lb
Example 3: Convert 3 Liters to Milliliters
- Step 1: Base unit (liter)
3 L - Step 2: Convert to milliliters
3 × 1000 = 3000 mL
