About the kilograms to grams converter
To convert kilograms to grams, multiply by 1,000; to convert back, multiply by 0.001. For example, 1.5 kg is about 1,500 g. Displayed factors and results may be rounded.
Kilogram labels are used for luggage allowances, bulk ingredients and body mass. Converting a whole or fractional kilogram into smaller units is useful when a scale or recipe expects a finer denomination. Keep the measurement's original precision instead of assuming every displayed digit was measured.
gram: 1 g = 1/1,000 kg. The kilogram is the SI base unit of mass.
Both units are defined exactly. Calculations use 50 significant digits and round only for display.
How to convert kilograms to grams
Multiply kilograms by 1,000 to get grams, which moves the decimal point three places to the right. 1 kg = 1,000 g, 1.5 kg = 1,500 g and 0.25 kg = 250 g. Use it to weigh a kilogram amount on a gram scale or to split a bulk pack into portions.
Moving the decimal point three places
Kilo means one thousand (NIST), so the factor is exact. Shift the point three places right, adding zeros at the end when you run out of digits:
- 1.5 kg → 1.500 → 1,500 g
- 0.025 kg → 25 g
- 0.0025 kg → 2.5 g; a gram answer can have decimals too.
Watch the digits after the point. 1.005 kg is 1,005 g, 1.05 kg is 1,050 g and 1.5 kg is 1,500 g: each has a different number of grams beyond the first kilogram.

Splitting a pack into portions
Convert to grams, then divide. A 1 kg bag shared into three equal portions is 1/3 kg each, or 333.333333333 g, so weigh out 333 g per portion.
Amounts written in kilograms and grams need the grams added, not tacked on after the point. 2 kg 75 g is 2,000 + 75 = 2,075 g; 2.75 kg would be 2,750 g.
To find what is inside a package, subtract the packaging. A 1.25 kg parcel with 0.18 kg of packaging holds 1.07 kg, or 1,070 g, of contents.
Kilograms to milligrams
The kilogram is the SI base unit of mass (BIPM). A gram is a thousandth of it and a milligram a millionth, so 1 kg = 1,000,000 mg.
Medicine and supplement labels use mg, and misreading mg as g is a thousandfold error.
Common mistakes
- Moving the point the wrong way. 2 kg is 2,000 g, not 0.002 g. Grams are the smaller unit, so the gram figure is always the bigger number.
- Reading the decimal part as grams. In 1.5 kg, the .5 is half a kilogram (500 g), not 5 g.
- Rounding the kilograms first. 1.25 kg rounded to 1.3 kg becomes 1,300 g, 50 g more than the real 1,250 g. Convert, then round.
- Expecting more precision than the scale has. A scale accurate to ±0.002 kg is accurate to ±2 g, whatever unit it displays.
Related conversions
Use grams to kg for the reverse direction and kg to lbs for pounds. The weight converter handles milligrams and ounces, and it accepts a typed unit such as 1.25 kg.
