How many grams in a kilogram?

One kilogram equals exactly 1,000 grams. Type a value in either box below and the other updates as you type — kilograms to grams or grams to kilograms, including values like 0.25 or 1.5. Below the converter there's a cooking chart with the weights recipes actually use: butter, flour, sugar, meat and the packet sizes you see at the supermarket.

What Is This Tool?

The kilogram is the base unit of mass in the metric system, and a gram is one thousandth of it — so 1 kg = 1,000 g. Supermarkets price by the kilogram, recipes measure by the gram, and kitchen scales flip between the two, which keeps this conversion in constant daily use.

The arithmetic is just moving the decimal point three places, but the questions come in awkward shapes: how many grams is 0.75 kg of meat, how many kilograms is 250 g of butter, whether 1,500 g of flour is enough when the recipe says 1.5 kg.

Why Use It?

Bidirectional and instant: type in either field and the other converts as you type.
Handles real recipe values: 0.25 kg, 250 g, 1.5 kg — decimals and everything in between.
Cooking chart included: butter, flour, sugar and meat weights pre-converted.
Exact by definition: 1 kg = 1,000 g, no rounding involved.

How to Use

Type a value in the kilograms field to see grams — or type grams to see kilograms.
Decimals work as expected: 0.25 kg, 1.5 kg, 250 g, 750 g.
For recipe weights, check the cooking chart below the converter.
For scaling a recipe, convert everything to grams first, then multiply.

Example

Input

1.5 kg (a bag of flour)

Output

1,500 g

1.5 × 1,000 = 1,500 g — enough for a recipe calling for 500 g three times over.

Common cooking weights in kilograms and grams

Kilograms	Grams	Typical item
0.1 kg	100 g	Chocolate bar
0.25 kg	250 g	Pack of butter
0.5 kg	500 g	Pack of pasta / minced meat
0.75 kg	750 g	Large yogurt tub
1 kg	1,000 g	Bag of sugar / bag of rice
1.5 kg	1,500 g	Bag of flour
2 kg	2,000 g	Whole chicken
5 kg	5,000 g	Large bag of rice / potatoes

Where this fits in real workflows

Baking is the sharpest use case: recipes measure flour, sugar and butter in grams, but you buy them in kilogram bags — and doubling or halving a recipe is safest done entirely in grams. The same conversion runs shopping math (price per kg vs the 400 g pack in your hand) and postage, where carriers charge by the kilogram but weigh in grams.

For volumes rather than weights (milk, water, stock in ml and liters), the liter ↔ milliliter converter is the companion tool.

Frequently Asked Questions

1 kilogram = 1,000 grams exactly. So 0.5 kg = 500 g, 0.25 kg = 250 g, and 2 kg = 2,000 g. To convert kilograms to grams, multiply by 1,000 (move the decimal point three places right).

How do I convert grams back to kilograms?

Divide by 1,000 (move the decimal point three places left). For example 250 g = 0.25 kg and 750 g = 0.75 kg. Supermarket price tags per kilogram work the same way: 400 g of cheese is 0.4 kg.

How many grams is half a kilo?

Half a kilogram is 500 grams. A quarter kilo is 250 g, and three quarters is 750 g — the three fractions recipes and market stalls use most often.

Are grams a unit of weight or mass?

Strictly, grams and kilograms measure mass, and weight is the force gravity exerts on that mass. In everyday life on Earth the distinction doesn't change any numbers — your kitchen scale reads grams either way — but it's why scientists say "mass" where shoppers say "weight".
