Convert Slugs to Kilograms
1 slug is 14.59 kg. One slug is exactly 14.5939029372 kilograms.
One slug is 14.593903 kilograms. To convert slugs to kilograms, multiply by 14.593903; to go the other way, divide by 14.593903 or multiply by 0.068521766. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Handbook 44. The mass that one pound-force accelerates at one foot per second squared — 32.174 pounds.

How do you convert slugs to kilograms? The converter and the working
- 1.Take the measurement in slugs.
- 2.Multiply by 14.593903 — that is how many kilograms fit in one slug.
- 3.To go back the other way, divide by 14.593903, or multiply by 0.068521766.
Worked example: 25 slugs to kilograms
- Formula
- slug × 14.593903 = kg
- Arithmetic
- 25 × 14.593903 = 364.85 kg
- Answer
- 25 slug = 364.85 kg
The factor is rounded for display; the figure above is computed from the full value.

The slug exists so that F = ma works in feet and pounds
A pound is a unit of mass and a pound-force is a unit of force, and in a system where they share a name Newton’s second law needs a conversion constant. The slug removes it: it is the mass one pound-force accelerates at one foot per second squared, which makes it 32.174 pounds, or 14.5939 kg. American engineering statics uses it for exactly that reason, and nothing else does.

What is a slug?
The mass that one pound-force accelerates at one foot per second squared — 32.174 pounds. It exists so that F = ma works in US customary units without a conversion constant, and it is why American engineering statics is not simply pounds.
What is a kilogram?
The SI base unit of mass, defined since 2019 by fixing the Planck constant rather than by a metal cylinder in Paris.
How many kilograms are in a slug?
One slug is 14.593903 kilograms. Going the other way, one kilogram is 0.068521766 slugs. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
