Understanding the Conversion Formula
The calculator uses a simple and consistent method based on base unit conversion.
Step 1: Convert to Base Unit
Each category has a base unit:
- Length → Meter (m)
- Weight → Gram (g)
- Volume → Milliliter (ml)
Formula:
Base Value = Amount × Conversion Factor (from unit to base unit)
Step 2: Convert to Target Unit
Final Result = Base Value ÷ Conversion Factor (target unit)
Conversion Factors Explained
Here are the standard conversion values used:
Length
| Unit | Factor (to meter) |
|---|---|
| mm | 0.001 |
| cm | 0.01 |
| m | 1 |
| km | 1000 |
Weight
| Unit | Factor (to gram) |
|---|---|
| g | 1 |
| kg | 1000 |
Volume
| Unit | Factor (to milliliter) |
|---|---|
| ml | 1 |
| l | 1000 |
Important Rule: Same Category Conversion
This calculator only allows conversions within the same category.
✔ Allowed:
- cm → m
- kg → g
- ml → l
❌ Not Allowed:
- cm → kg
- liter → meter
This ensures logical and accurate results.
Example Conversions
Example 1: Length Conversion
Convert 150 centimeters to meters
Step 1: Convert to base (meters)
150 × 0.01 = 1.5 m
Step 2: Convert to target (meters)
Result = 1.5 m
Example 2: Weight Conversion
Convert 2.5 kilograms to grams
Step 1: Convert to grams
2.5 × 1000 = 2500 g
Result = 2500 grams
Example 3: Volume Conversion
Convert 750 milliliters to liters
Step 1: Convert to liters
750 ÷ 1000 = 0.75 L
Result = 0.75 liters
