Basic Weight Conversion Formulas
Here are the standard formulas used by the calculator.
Gram to Kilogram
kg=1000g
Example:
5000 g = 5 kg
Kilogram to Gram
g=kg×1000
Example:
2 kg = 2000 g
Gram to Milligram
mg=g×1000
Example:
3 g = 3000 mg
Ounce to Gram
g=oz×28.3495
Example:
5 oz = 141.7475 g
Pound to Gram
g=lb×453.592
Example:
2 lb = 907.184 g
Stone to Gram
g=st×6350.29
Example:
1 st = 6350.29 g
Example Conversions
Here are some practical examples of how the calculator works.
Example 1: Convert Kilograms to Pounds
Suppose you want to convert 10 kilograms into pounds.
Step 1:
1 kilogram = 2.20462 pounds
Step 2:
10 × 2.20462 = 22.0462 lb
Result:
10 kg = 22.0462 lb
Example 2: Convert Ounces to Grams
Suppose you have 8 ounces of flour.
Formula:
8 × 28.3495
Result:
226.796 g
Example 3: Convert Milligrams to Grams
Suppose a medicine label shows 2500 mg.
