How to convert ounces to kilograms (oz to kg)

The formula for converting ounces to kilograms is: kg = oz ÷ 35.274. To calculate the ounce value in kilograms first substitute the ounce value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 ounce in kilograms we follow these steps:

kg = oz ÷ 35.274

kg = 1 ÷ 35.274

kg = 0.0283494925440834609060497817089

In other words, 1 ounce is equal to 0.0283494925440834609060497817089 kilograms.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 5 ounces to kilograms is:

  1. Understand the conversion formula: kg = oz ÷ 35.274
  2. Substitute the required value. In this case we substitute 5 for oz so the formula becomes: kg = 5 ÷ 35.274
  3. Calculate the result using the provided values. In our example the result is: 5 ÷ 35.274 = 0.141747462720417304530248908545 kg

In summary, 5 ounces is equal to 0.141747462720417304530248908545 kilograms.

Converting kilograms to ounces

In order to convert the other way around i.e. kilograms to ounces, you would use the following formula: oz = kg × 35.274. To convert kilograms to ounces first substitute the kilogram value into the above formula, and then execute the calculation. If we wanted to calculate 1 kilogram in ounces we follow these steps:

oz = kg × 35.274

oz = 1 × 35.274

oz = 35.274

Or in other words, 1 kilogram is equal to 35.274 ounces.

Conversion Unit Definitions

What is a Ounce?

The ounce, symbolized as "oz", is a unit of weight commonly used in various countries, including the United States and the United Kingdom. It is part of the avoirdupois system of measurement, which is one of the systems in the U.S. customary system.
Here are some more details about the ounce:
  1. Weight Measurement: The ounce is primarily used to measure weight. It is a smaller unit of weight compared to pounds and kilograms. One ounce is equal to 1/16th of a pound or approximately 28.35 grams. Conversely, one pound is equal to 16 ounces.

  2. Avoirdupois System: The ounce is part of the avoirdupois system, which is commonly used for everyday weight measurements in countries like the United States. In this system, the pound is the primary unit, and it is divided into ounces. The ounce is further subdivided into smaller units like drams and grains.

  3. Fluid Ounce: It's important to note that there is also a fluid ounce (symbolized as "fl oz"), which is used to measure volume in the context of liquids. However, in this context, we are specifically discussing the ounce as a measure of weight.

  4. Common Uses: The ounce is commonly used in various contexts, such as measuring the weight of food items, ingredients in cooking and baking, and small objects. It is also used in commercial packaging and for measuring the weight of certain goods and products.

  5. Symbol: The symbol for ounce is "oz". For example, a weight measurement of 8 ounces would be written as 8 oz.

  6. International Usage: While the ounce is primarily used in the United States and a few other countries, it is not as widely adopted internationally. Most countries have transitioned to the metric system, where the gram and kilogram are the standard units of measurement for mass.

  7. Conversion: The ounce can be converted to other units of weight. For example, one ounce is equal to approximately 28.35 grams. Conversely, one gram is approximately 0.0353 ounces. It's important to use conversion factors or conversion tables to accurately convert between different units of weight.

What is a Kilogram?

The kilogram, symbolized as "kg," is the primary unit of mass in the International System of Units (SI). It is widely used around the world as a standard unit for measuring mass. The kilogram is defined based on a fundamental physical constant and is recognized as the base unit for mass in scientific and everyday contexts.
Here are some more details about the kilogram:
  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. Symbol: The symbol for kilogram is "kg." For example, a mass measurement of 2.5 kilograms would be written as 2.5 kg.

  6. 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.

  7. 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.
