Who decided 1kg is 1kg?
The kilogram was originally defined in 1795 during the French Revolution as the mass of one litre of water. The current definition of a kilogram agrees with this original definition to within 30 parts per million. In 1799, the platinum Kilogramme des Archives replaced it as the standard of mass.
How was the kilogram originally calculated?
A kilogram is very nearly equal (it was originally intended to be exactly equal) to the mass of 1,000 cubic cm of water. The pound is defined as equal to 0.45359237 kg, exactly. As originally defined, the kilogram was represented in the late 18th century by a solid cylinder of platinum.
How did they find the kilogram?
For 130 years, the kilogram has been defined as the exact weight of a cylinder of platinum-iridium held in a triple-locked vault in Paris. Metrologists — experts in the science of measurement — refer to the metal lump as the International Prototype Kilogram, or IPK.
Why 1kg is 1000g?
You must multiply the quantity in kgs by the conversion factor, which is 0.001. Here, the m in the gm is equivalent to the mass (m) in kg x 1000. So, 1 kg in grams will be 1 times 0.001, 1000 grams.
Why was the kilogram redefined?
The kilogram was redefined in order to create a precise, unchanging standard for its value, according to Henson. More than a century of cleanings and exposure to air had caused the original French prototype — known as the International Prototype of the Kilogram, or “Le Grand K” — to lose about 50 micrograms.
Does 1000g equal 1kg?
For every kilogram, there are 1000 grams. That means that the ratio between kilograms and grams is 1:1000. It also means 1 kilogram and 1000 grams are defined as being equal.
Does eating 1kg make you 1kg heavier?

Where is the true kilogram?
Currently, the kilogram has a very simple definition: It's the mass of a hunk of platinum-iridium alloy that's been housed at the International Bureau of Weights and Measures in Sèvres, France since 1889.
How was weight first measured?
When means for weighing were invented, seeds and stones served as standards. For instance, the carat, still used as a unit for gems, was derived from the carob seed.
What was the original kilogram made of?

Is 1kg equal to 100g?
There are 1000 grams in one kilogram, so to convert grams to kilograms, you simply divide the number of grams by 1000. Technically, this is "unit conversion" and looks like this in fully expanded form: 100 g . 1 k g 100 g = 100 g .
What is the new definition of 1 kg?
Or in other words, one kilogram is now defined to be the mass of 1.4755214 1040 photons at the cesium hyperfine frequency. This is illustrated in the figure: a microwave cavity with 1.4755214 1040 photons at the cesium frequency is heavier than an empty cavity by exactly one kg.
Is the kilogram getting lighter?
A loss of mass
The problem is that when these replicas from around the world are compared to Big K, metrologists have found slight differences in their masses. It isn't quite clear why — perhaps due to small diffusions of gas from the original — but the kilogram appears to be getting lighter.

Kilogram or simply “kg” is the mass of an object. It is same everywhere whether on earth or the moon. for e.g. If ur mass is 53 kg on the earth then u will remain 53kg on the moon also. “Weight” on the other hand is different for the earth and the moon since acceleration due to gravity is different for these places.

History. The word gramme was adopted by the French National Convention in its 1795 decree revising the metric system as replacing the gravet (introduced in 1793 simultaneously with a base measure called grave, of which gravet was a subdivision). Its definition remained that of the weight of a cubic centimetre of water.
