328 grams in kilograms

Conversion

328 grams is equivalent to 0.328 kilograms.^[1]

Conversion formula
How to convert 328 grams to kilograms?

We know (by definition) that: $1 g = 0.001 kg$

We can set up a proportion to solve for the number of kilograms.

\frac{1 g}{328 g} = \frac{0.001 kg}{x kg}

Now, we cross multiply to solve for our unknown $x$ :

x kg = \frac{328 g}{1 g} * 0.001 kg \to x kg = 0.328 kg

Conclusion: $328 g = 0.328 kg$

328 grams is equivalent to 0.328 kilograms

Conversion in the opposite direction

The inverse of the conversion factor is that 1 kilogram is equal to 3.04878048780488 times 328 grams.

It can also be expressed as: 328 grams is equal to $\frac{1}{3.04878048780488}$ kilograms.

Approximation

An approximate numerical result would be: three hundred and twenty-eight grams is about zero point three three kilograms, or alternatively, a kilogram is about three point zero four times three hundred and twenty-eight grams.

Units involved

This is how the units in this conversion are defined:

Grams

The gram is a metric system unit of mass. Originally defined as the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre, and at the temperature of melting ice. However, a gram is now defined as one one-thousandth of the SI base unit, the kilogram, or 1×10−3 kg, which itself is now defined, not in terms of grams, but as being equal to the mass of a physical prototype of a specific alloy kept locked up and preserved by the International Bureau of Weights and Measures. This is in the tradition by which many customary local reference standard stones, lengths (objects) and weights were required to periodically undergo comparison with the official nations standard referents, usually with a particular periodicity defined by the countries statuate laws.

Kilograms

The kilogram is the base unit of mass in the International System of Units (the Metric system) and is defined as being equal to the mass of the International Prototype of the Kilogram. The avoirdupois (or international) pound, used in both the imperial and US customary systems, is defined as exactly 0.45359237 kg, making one kilogram approximately equal to 2.2046 avoirdupois pounds. Other traditional units of weight and mass around the world are also defined in terms of the kilogram, making the IPK the primary standard for virtually all units of mass on Earth.
