2 grams (g) is equal to 0.002 kilograms (kg).
To convert grams to kilograms, you divide the number of grams by 1000 because one kilogram equals 1000 grams. So, 2 grams divided by 1000 gives 0.002 kilograms.

Conversion Formula
To convert grams to kilograms, you divide the grams value by 1000. The formula is:
kilograms = grams ÷ 1000
This works because the kilogram is a larger unit than gram by exactly 1000 times. Dividing by 1000 scales the smaller unit into the larger one.
Example: Convert 2 g to kg.
- Start with 2 grams.
- Divide 2 by 1000: 2 ÷ 1000 = 0.002.
- So, 2 grams equals 0.002 kilograms.
Conversion Example
- Convert 500 g to kg:
- Take 500 grams.
- Divide by 1000: 500 ÷ 1000 = 0.5.
- Result is 0.5 kilograms.
- Convert 1250 g to kg:
- Start with 1250 grams.
- Divide 1250 by 1000: 1250 ÷ 1000 = 1.25.
- Answer is 1.25 kilograms.
- Convert 75 g to kg:
- 75 grams divided by 1000: 75 ÷ 1000 = 0.075.
- So, 75 g equals 0.075 kg.
- Convert 3000 g to kg:
- 3000 grams divided by 1000: 3000 ÷ 1000 = 3.
- Therefore, 3 kilograms.

Conversion Definitions
Gram (g): The gram is a unit of mass in the metric system, equal to one thousandth of a kilogram. It is commonly used to measure small weights like food ingredients, precious metals, and scientific samples. One gram is approximately the mass of a paperclip.
Kilogram (kg): The kilogram is the base unit of mass in the International System of Units (SI). It equals 1000 grams. Kilograms are used for measuring heavier weights such as body weight, produce, and industrial materials. The kilogram is the only SI base unit still defined by a physical artifact.
Conversion FAQs
Can I convert grams to kilograms by multiplying?
No, when converting grams to kilograms, you divide the gram value by 1000. Multiplying would increase the number, which is incorrect because kilograms are larger units. For example, 2 g ÷ 1000 = 0.002 kg, not 2 × 1000.
Why is the conversion factor 1000 between grams and kilograms?
Because the metric system sets the kilogram as the base unit, and the gram as one-thousandth of a kilogram. That means 1 kg equals 1000 g, so conversion requires dividing or multiplying by 1000 depending on direction.
Are negative gram values valid when converting to kilograms?
Negative values in grams can appear in contexts like measuring change in weight or differences. The conversion process remains the same; divide by 1000. For example, -23 g is -0.023 kg. Negative mass is not physically possible, but useful in calculations.
Can decimals in grams cause errors in the conversion?
Decimals are supported and expected in conversions. When converting decimals in grams, divide by 1000 normally. For example, 2.5 g ÷ 1000 = 0.0025 kg. Precision depends on decimal places used in calculations or display.
Is there any situation where grams and kilograms are used interchangeably?
They are not interchangeable because they represent different scales of mass. Using the wrong unit can cause confusion or errors, especially in science and commerce. Always convert properly before comparing or combining values.
