Kilograms to Grams Converter (kg to g)
1 kg = 1,000 g exactly. Convert kilograms to grams for recipes, food sold by the kilo and sports equipment, with kg to g and g to kg charts.
Gram (g) = Kilogram (kg) × 1000
Kilogram (kg): The kilogram is the SI base unit of mass. Since 2019 it has been defined by fixing the value of the Planck constant, replacing the platinum-iridium prototype kept near Paris.
Gram (g): The gram is one thousandth of a kilogram, the SI base unit of mass. It is used worldwide for food, postage and small quantities of almost anything.
| Kilogram (kg) | Gram (g) |
|---|---|
| 1 | 1000 |
| 5 | 5000 |
| 10 | 10000 |
| 25 | 25000 |
| 50 | 50000 |
| 100 | 100000 |
Shops and recipes outside the US often price or list ingredients by the kilogram, while kitchen scales and most recipe steps work in grams. Multiplying by 1,000 turns 1.25 kg of flour into 1,250 g, and the same step applies to parcels, produce and anything else weighed in metric units.
The charts concentrate on fractions of a kilogram, because that is where mistakes happen: 0.125 kg is 125 g, not 1,250 g. Sports rules give a further example, since athletics throwing implements are specified by mass and the lighter ones are easier to picture in grams: a men's javelin is set at 0.8 kg in the rules, but 800 g is the figure most people can imagine.
How to use this tool
- Type a value in the Kilogram box to see it in grams, or type in the Gram box to convert the other way.
- Press ⇄ to swap the two units, or Load example for a typical value.
- Check the charts below for common values; for other units, open the Weight & Mass converter.
Formula
Gram (g) = Kilogram (kg) × 1000
Kilogram (kg) = Gram (g) × 0.001
Both factors come from exact definitions: 1 gram = 0.001 kilograms and 1 kilogram = 1000 grams (shown to 12 significant digits).
Example
Two conversions worked with the same factors the converter uses:
1.25 kg × 1000 = 1250 g
450 g × 0.001 = 0.45 kg

Quick mental estimate
Multiply by 1,000 by sliding the decimal point right three digits: 1.25 kg → 1,250 g. Fractions are worth memorizing too: a quarter kilo is 250 g and a half kilo is 500 g. The result is exact.
Use the converter or the charts when the exact figure matters.
The two units
Kilogram (kg): The kilogram is the SI base unit of mass. Since 2019 it has been defined by fixing the value of the Planck constant, replacing the platinum-iridium prototype kept near Paris.
Gram (g): The gram is one thousandth of a kilogram, the SI base unit of mass. It is used worldwide for food, postage and small quantities of almost anything.
Frequently asked questions
How many grams are in a kilo?
Exactly 1,000. "Kilo" is everyday shorthand for kilogram, so 1 kilo = 1,000 g, and half a kilo is 500 g.
Why is the kilogram, not the gram, the SI base unit?
It is a historical choice. The standard sanctioned in 1889 was a kilogram-sized platinum-iridium cylinder, and the SI kept the kilogram as its base unit when it was redefined through the Planck constant in 2019. The gram is defined from it as one thousandth, and every other metric mass, from the milligram to the tonne, follows by powers of ten.
How do I work out a price for 350 g when the shop shows a price per kg?
Convert the amount to kilograms and multiply: 350 g is 0.35 kg, so the cost is 0.35 times the per-kg price. A price of 12 per kg comes to 4.20 for 350 g. The same method works for any metric price: divide the grams by 1,000 first.
How precise is the result?
The converter uses the exact definitions above with browser floating-point arithmetic and shows up to 12 significant digits. The charts round to four decimal places for reading.
