## 9.9 kg to lbs

Before we move on to the practice - that is 9.9 kg how much lbs conversion - we will tell you some theoretical information about these two units - kilograms and pounds. So we are starting.

## 9.9 kgs in pounds

We will start with the kilogram. The kilogram is a unit of mass. It is a basic unit in a metric system, in formal International System of Units (in abbreviated form SI).

From time to time the kilogram is written as kilogramme. The symbol of the kilogram is kg.

Firstly, the definition of a kilogram was formulated in 1795. The kilogram was described as the mass of one liter of water. This definition was not complicated but difficult to use.

Later, in 1889 the kilogram was defined by the International Prototype of the Kilogram (in abbreviated form IPK). The IPK was prepared of 90% platinum and 10 % iridium. The IPK was used until 2019, when it was substituted by a new definition.

Today the definition of the kilogram is based on physical constants, especially Planck constant. Here is the official definition: “The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015×10−34 when expressed in the unit J⋅s, which is equal to kg⋅m2⋅s−1, where the metre and the second are defined in terms of c and ΔνCs.”

One kilogram is 0.001 tonne. It is also divided into 100 decagrams and 1000 grams.

You learned something about kilogram, so now we can move on to the pound. The pound is also a unit of mass. We want to point out that there are more than one kind of pound. What are we talking about? For instance, there are also pound-force. In this article we want to centre only on pound-mass.

The pound is in use in the Imperial and United States customary systems of measurements. Of course, this unit is used also in other systems. The symbol of this unit is lb or “.

The international avoirdupois pound has no descriptive definition. It is defined as exactly 0.45359237 kilograms. One avoirdupois pound is divided into 16 avoirdupois ounces or 7000 grains.

The avoirdupois pound was enforced in the Weights and Measures Act 1963. The definition of the pound was given in first section of this act: “The yard or the metre shall be the unit of measurement of length and the pound or the kilogram shall be the unit of measurement of mass by reference to which any measurement involving a measurement of length or mass shall be made in the United Kingdom; and- (a) the yard shall be 0.9144 metre exactly; (b) the pound shall be 0.45359237 kilogram exactly.”
