1 kilogram is approximately equal to 0.0685218 slugs.
The conversion from kilograms to slugs involves the relationship between mass units used in the metric system and the imperial system. Kilograms measure mass in the metric system, while slugs measure mass in the imperial system, primarily used in the United States for engineering purposes. The conversion factor is based on the gravitational constant and unit definitions.

Conversion Formula
The formula for converting kilograms (kg) to slugs uses a fixed conversion factor:
slug = kilogram × 0.0685218
This factor exists because 1 slug is defined as the mass that accelerates by 1 ft/s² when a force of 1 pound-force (lbf) is applied to it. Since 1 kg is a mass unit in metric, converting it requires accounting for the difference in gravitational constants and unit systems.
Example calculation for 1 kg:
- Start with 1 kg
- Multiply by conversion factor: 1 × 0.0685218
- Result: 0.0685218 slugs
Conversion Example
- Convert 5 kg to slugs:
- Multiply 5 by 0.0685218
- 5 × 0.0685218 = 0.342609 slugs
- Therefore, 5 kg = 0.3426 slugs (rounded)
- Convert 10.5 kg to slugs:
- 10.5 × 0.0685218 = 0.7199789
- Result is about 0.7200 slugs
- Convert 0.25 kg to slugs:
- 0.25 × 0.0685218 = 0.01713045
- Approximate as 0.0171 slugs
- Convert 15 kg to slugs:
- 15 × 0.0685218 = 1.027827
- About 1.0278 slugs

Conversion Definitions
Kilogram (kg): Kilogram is the base unit of mass in the metric system, defined as the mass of the International Prototype Kilogram. It is widely used in science and everyday measurements around the world, representing approximately 2.20462 pounds in the imperial system.
Slug: Slug is a unit of mass, primarily used in the imperial system in the United States. It equals the mass that accelerates by 1 ft/s² under a force of 1 pound-force. One slug equals approximately 14.5939 kilograms, making it much larger than a kilogram.
Conversion FAQs
Why is the slug unit used instead of kilograms in some fields?
Slug is used in fields like aerospace and mechanical engineering within the United States because it fits better with imperial units of force and acceleration (pounds and feet per second squared). This makes calculating forces and motions in those units more straightforward than converting every time from kilograms.
Can I convert slugs back into kilograms easily?
Yes, to convert slugs into kilograms, multiply the value in slugs by about 14.5939. This reverses the conversion process. However, make sure you use the exact conversion factor to avoid errors, especially in precise engineering calculations.
Is the conversion factor between kg and slug exact or approximate?
The factor 0.0685218 is an approximation based on standard gravity and unit definitions. Small variations in local gravity or rounding can cause very slight differences, but for general use, this factor is accurate enough.
Does converting 1 kg to slug change depending on location?
No, the conversion from kg to slug depends on unit definitions, not location. However, the slug is linked to pound-force and acceleration, which assumes standard gravity. So, in places with different gravitational acceleration, forces might vary slightly, but mass conversions remain consistent.
How do negative mass values in the conversion chart make sense?
Negative mass values in the chart represent theoretical or calculation results rather than physical reality, since mass can’t be negative. They might appear when dealing with certain physics equations or simulations that use signed values for direction or reference.
