Kilogram to Gram Converter (kg to g)
Instantly convert between kilograms and grams using this precise tool. Essential for cooking, scientific research, and industrial applications. 100% free with no registration required.
Conversion Formula
1 kilogram (kg) = 1000 grams (g)
To convert kilograms to grams:
grams = kilograms × 1000
Example: 2.5 kg × 1000 = 2500 g
Kilogram to Gram Conversion Table
| Kilograms (kg) | Grams (g) |
|---|---|
| 0.001 kg | 1 g |
| 0.01 kg | 10 g |
| 0.05 kg | 50 g |
| 0.1 kg | 100 g |
| 0.25 kg | 250 g |
| 0.5 kg | 500 g |
| 1 kg | 1000 g |
| 1.5 kg | 1500 g |
| 2 kg | 2000 g |
| 5 kg | 5000 g |
| 10 kg | 10000 g |
Practical Examples
- Cooking ingredients: 0.5 kg = 500 g (e.g., sugar for baking)
- Luggage weight: 20 kg = 20000 g (typical airline limit)
- Body weight: 75 kg = 75000 g (average adult weight)
Professional Applications
- Culinary arts: Measuring ingredients for large-scale recipes
- Scientific research: Weighing samples in laboratories
- Pharmacy: Dosing medications accurately
- Manufacturing: Weighing bulk materials for production
Definition and Background
What is a Kilogram?
A kilogram (kg) is the base unit of mass in the International System of Units (SI). It was originally defined in 1795 as:
- The mass of one liter of water at 4°C
- Now defined by the Planck constant (since 2019)
What is a Gram?
A gram (g) is a metric unit of mass equal to one-thousandth of a kilogram. The name comes from:
上- Latin “gramma”: meaning small weight
- Part of the metric system established during the French Revolution
Metric System Hierarchy
| Unit | Symbol | Kilograms |
|---|---|---|
| Milligram | mg | 0.000001 kg |
| Gram | g | 0.001 kg |
| Hectogram | hg | 0.1 kg |
| Kilogram | kg | 1 kg |
| Tonne | t | 1000 kg |
Frequently Asked Questions
Why would I use kilograms instead of grams?
Kilograms are suitable for measuring larger masses, such as bulk ingredients or body weight, where grams would result in large numbers.
How precise is kilogram measurement?
Kilograms are less precise than grams (1 kg = 1000 g), but they are practical for measuring larger quantities where high precision is not critical.
What’s the history of the kilogram?
Introduced during the French Revolution as part of the metric system, originally defined as the mass of one liter of water, now based on the Planck constant.
Are kilograms used worldwide?
Kilograms are widely used globally in countries adopting the metric system, though pounds are more common in the US for some applications.
