Convert Kilograms to Slugs
1 kilogram is 0.07 slug. One kilogram is exactly 0.0685217658568 slugs.
One kilogram is 0.068521766 slugs. To convert kilograms to slugs, multiply by 0.068521766; to go the other way, divide by 0.068521766 or multiply by 14.593903. 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 SI base unit of mass, defined since 2019 by fixing the Planck constant rather than by a metal cylinder in Paris.

How do you convert kilograms to slugs? The converter and the working
- 1.Take the measurement in kilograms.
- 2.Multiply by 0.068521766 — that is how many slugs fit in one kilogram.
- 3.To go back the other way, divide by 0.068521766, or multiply by 14.593903.
Worked example: 25 kilograms to slugs
- Formula
- kg × 0.068521766 = slug
- Arithmetic
- 25 × 0.068521766 = 1.71 slug
- Answer
- 25 kg = 1.71 slug
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 kilogram?
The SI base unit of mass, defined since 2019 by fixing the Planck constant rather than by a metal cylinder in Paris.
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.
How many slugs are in a kilogram?
One kilogram is 0.068521766 slugs. Going the other way, one slug is 14.593903 kilograms. 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.
