1 kilogram is approximately equal to 0.06852 slugs.
The kilogram is a unit of mass used internationally, while the slug is a mass unit used mainly in the British engineering system. Converting between them requires a fixed factor based on the relationship between mass, force, and acceleration in these systems.

Conversion Formula
The formula to convert kilograms (kg) to slugs is based on the fact that 1 slug equals 14.5939 kilograms. So, to find the equivalent slug value, you divide the mass in kilograms by 14.5939.
Formula:
slug = kilogram ÷ 14.5939
Why it works: the slug is a unit used in the Imperial system that relates mass to the force of gravity in feet per second squared. Since the kilogram belongs to the metric system, the conversion bridges the two by using the constant 14.5939 kg per slug.
Example calculation for 1 kg:
1 kg ÷ 14.5939 = 0.06852 slug
Conversion Example
- Convert 5 kg to slug:
- Start with 5 kg.
- Divide 5 by 14.5939: 5 ÷ 14.5939 = 0.3426 slug.
- Result: 5 kg equals about 0.3426 slugs.
- Convert 10 kg to slug:
- Take 10 kg.
- Divide 10 by 14.5939: 10 ÷ 14.5939 = 0.6852 slug.
- So, 10 kg is 0.6852 slugs.
- Convert 0.5 kg to slug:
- Half a kilogram is 0.5 kg.
- Divide 0.5 by 14.5939: 0.5 ÷ 14.5939 = 0.03426 slug.
- Half a kilogram equals approximately 0.03426 slugs.
- Convert 20 kg to slug:
- Start with 20 kg.
- Divide 20 by 14.5939: 20 ÷ 14.5939 = 1.3704 slug.
- Therefore, 20 kg equals about 1.3704 slugs.

Conversion Definitions
Kilogram (kg): The kilogram is the base unit of mass in the International System of Units (SI). It represents the mass of the international prototype kilogram, a platinum-iridium cylinder stored in France. Kilograms measure mass, not weight, and are commonly used worldwide for scientific and everyday purposes.
Slug: The slug is a unit of mass used in the Imperial system, primarily in the United States. Defined as the mass that accelerates by 1 ft/s² when a force of one pound-force is applied, it connects mass and force under gravity. One slug equals about 14.5939 kilograms.
Conversion FAQs
Why do kilograms and slugs differ in size so much?
Kilograms and slugs differ because they belong to different measurement systems that use distinct base units and relationships between force and mass. The slug is defined based on the pound-force and gravity in feet per second squared, making it larger than a kilogram by a factor of about 14.6.
Can I convert weight measured in kilograms to slugs directly?
Weight and mass are different; kilograms measure mass, while slugs also measure mass but defined differently. If you have weight in kilograms-force, you need to convert it properly. Only when dealing with mass you can convert kilograms directly to slugs using the division by 14.5939.
Is the conversion factor always 14.5939?
Yes, the conversion factor from kilograms to slugs is constant at approximately 14.5939. This is because it depends on fixed physical constants relating mass to force in the Imperial and SI systems. This factor will not change unless definitions of units are altered.
Why is the slug not used as widely as kilograms?
The slug is mostly used in limited fields like aerospace and some engineering in the US, while kilograms are part of the SI system used worldwide. The global adoption of SI units, ease of use, and international standardization makes kilograms more common than slugs.
How precise is the conversion from kg to slug?
The conversion factor is very precise based on physical constants, but practical measurements might introduce small errors. For most engineering and scientific work, using 14.5939 as divisor gives enough accuracy for converting kilograms to slugs.
