What are kilograms (kg)?

The kilogram (kg) serves as a fundamental unit within the metric system for measuring object weight. A single kilogram consists of 1000 grams, positioning it as a higher-level measurement unit compared to grams, which are employed for lighter weights.

The kilogram finds widespread application in physics and engineering disciplines, as well as in everyday usage across nations that utilize the metric system.

What are ounces (oz)?

The ounce is a unit of weight in both the imperial and US customary systems. The abbreviated notation for ounce is oz. One ounce equals approximately 28.3495 grams or 0.0283495 kilograms.

There are 16 ounces in one pound (lb), making the ounce a smaller unit of weight measurement commonly used for measuring lighter items such as food ingredients, postal packages, and precious metals.

How do you convert kilograms (kg) to ounces (oz)?

The Conversion Formula

To convert kilograms to ounces, multiply the number of kilograms by 35.274:
Formula: Ounces = Kilograms × 35.274

Step-by-Step Process

• Take your weight in kilograms
• Multiply by 35.274
• The result is your weight in ounces

Examples

• 1 kg to oz:
  1 kg × 35.274 = 35.274 oz
• 2 kg to oz:
  2 kg × 35.274 = 70.548 oz
• 0.5 kg to oz:
  0.5 kg × 35.274 = 17.637 oz
• 5 kg to oz:
  5 kg × 35.274 = 176.37 oz
• 10 kg to oz:
  10 kg × 35.274 = 352.74 oz

Quick Reference

• 1 kg = 35.274 oz
• 1 oz = 0.0283495 kg
• 0.453592 kg (1 lb) = 16 oz

Why This Conversion Works

The conversion factor 35.274 is the exact number of ounces in one kilogram. This is an internationally recognized standard used in science, commerce, and everyday measurements. Since one kilogram equals approximately 1000 grams, and one ounce equals approximately 28.3495 grams, one kilogram equals 1000 ÷ 28.3495 = 35.274 ounces.

Tips for Mental Math

For quick estimates, remember that:

1 kg ≈ 35 oz
0.5 kg ≈ 17.5 oz (approximately half of 35)
2 kg ≈ 70 oz
10 kg ≈ 350 oz

Since kilograms are larger than ounces, the resulting ounce value will always be much larger than the kilogram value.
