As a global supplier of magnetic wheels for wall-climbing robots, we ship our products everywhere. However, you may have noticed that our technical specification sheets list Pull Force (Adhesion) in kgf.
If you are an engineer in the United States, you likely think in pounds (lbs).
Here is a quick guide to understanding our ratings and why the conversion is simpler than you think.
What is kgf?
kgf (Kilogram-force) is a metric unit of force.
- It represents the force exerted by gravity on a mass of one kilogram.
- It is the standard unit used in Asia and Europe for measuring magnetic strength.
What is lbf?
lbf (Pound-force) is the standard unit used in the United States.
- When a US engineer asks, "How much weight can this magnet hold?", they are asking for lbf.
The "Language" of Force
The difference isn't just math; it's cultural.
- In the Metric world, a 10 kgf wheel feels intuitive.
- In the US, that same number might require mental math to visualize.
We want to make sure you understand exactly how powerful our permanent magnets are, regardless of your location.
The Golden Rule: The 2.2 Conversion
Converting our specs to your preferred unit is easy. The ratio is roughly 2.2.
1 kgf ≈ 2.205 lbf
A Practical Example
Let's say one of our magnetic wheels is rated at 10 kgf.
To find the US rating:
Result: A 10 kgf wheel provides approximately 22 pounds of holding force.
Summary
We test in kgf to maintain global consistency, but we design for universal strength. Whether you calculate in kilograms or pounds, our magnetic wheels provide the reliable adhesion your robot needs to stay on the wall.
