How to convert kilograms to stone (kg to st)
The formula for converting kilograms to stone is: st = kg × 0.157473. To calculate the kilogram value in stone first substitute the kilogram value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 kilogram in stone we follow these steps:
st = kg × 0.157473
st = 1 × 0.157473
st = 0.157473
In other words, 1 kilogram is equal to 0.157473 stone.
Let's take a look at an example. The step-by-step process to convert 9 kilograms to stone is:
- Understand the conversion formula: st = kg × 0.157473
- Substitute the required value. In this case we substitute 9 for kg so the formula becomes: st = 9 × 0.157473
- Calculate the result using the provided values. In our example the result is: 9 × 0.157473 = 1.417257 st
In summary, 9 kilograms is equal to 1.417257 stone.
Converting stone to kilogramsTo convert kilograms to stone (kg to st), you can divide the number of kilograms by 6.35. This is the conversion factor for kilograms to stone and it is derived from the fact that there are 6.35 kilograms in one stone. Here is the formula for calculating stone in kilograms:Number of kilograms = number of stone × 6.35029318
Conversion Unit Definitions
What is a Kilogram?
Mass Measurement: The kilogram is used to measure mass, which is the amount of matter in an object. It is the base unit of mass in the International System of Units (SI) and is considered one of the seven fundamental SI units.
International System of Units (SI): The kilogram is part of the metric system and is used globally as a standard unit of mass measurement. The metric system provides a decimal-based system of measurement, facilitating easy conversion between different metric units.
Definition: Until recently, the kilogram was defined by a physical artifact known as the International Prototype of the Kilogram (IPK), a platinum-iridium cylinder kept in France. However, in 2019, the kilogram was redefined based on a fundamental constant of nature known as the Planck constant. This new definition ensures the stability and reproducibility of the kilogram.
Conversion: The kilogram can be easily converted to other metric units. For example, one kilogram is equal to 1,000 grams or 1,000,000 milligrams. Conversely, one gram is equal to 0.001 kilograms, and one milligram is equal to 0.001 grams or 0.000001 kilograms.
Symbol: The symbol for kilogram is "kg." For example, a mass measurement of 2.5 kilograms would be written as 2.5 kg.
Common Uses: The kilogram is widely used in scientific research, engineering, industry, commerce, and everyday life for measuring mass. It is used in fields such as physics, chemistry, manufacturing, agriculture, and healthcare, among others.
International Usage: The kilogram is the standard unit of mass measurement in most countries globally, as it is part of the International System of Units (SI). Its usage promotes consistency, compatibility, and ease of communication across different regions and scientific disciplines.
What is a Stone?
Weight Measurement: The stone is used to measure weight. One stone is equal to 14 pounds or approximately 6.35 kilograms. It is a larger unit of weight compared to pounds and kilograms.
Common Usage: The stone is primarily used in the United Kingdom and Ireland, where it is commonly used for personal weight measurement and in some industries for the sale of bulk goods. It is often used in casual conversation, particularly when referring to a person's body weight.
Symbol: The symbol for stone is "st". For example, a weight measurement of 10 stone would be written as 10 st.
Subdivisions: While the stone is commonly used on its own, it can be further divided into smaller units. The most common subdivision of a stone is the pound. One stone is equal to 14 pounds, and each pound is further subdivided into ounces.
Conversion: The stone can be converted to other units of weight. For example, one stone is equal to approximately 6.35 kilograms or 224 ounces. Conversely, one kilogram is approximately 0.1575 stones.
International Usage: The stone is primarily used in the United Kingdom and Ireland. It is not as widely adopted internationally, as most countries have transitioned to the metric system, where kilograms and grams are the standard units of weight measurement.
Informal Use: It's important to note that the stone is often used in casual conversation, particularly in the United Kingdom, as a way to discuss personal weight. However, in formal settings and in scientific or technical contexts, the kilogram or gram is generally used.
