How to Convert Hectometer to Sun's Radius
To convert hm to meters: multiply by 100. To convert hm to km: divide by 10.
1 hm = 100 m = 0.1 km = 10 dam. One square hectometer (hm²) equals one hectare.
For example, 1 Hectometer (hm) = 1.436080e-7 Sun's Radius (R☉).

About Hectometer (hm)
Definition
The hectometer is a unit of length equal to 100 meters, or one tenth of a kilometer.
Mathematical Relationship
1 hm = 100 m = 0.1 km = 10 dam. One square hectometer (hm²) equals one hectare.
Conversion Formula
To convert hm to meters: multiply by 100. To convert hm to km: divide by 10.
Practical Applications
The hectare (1 hm²) is its most common derived application. Occasionally used for short road distances.
Interesting Facts
A 100-meter Olympic sprint is exactly 1 hectometer. The hectare = 1 hm² is far more famous than the hectometer itself.
Common Mistakes
Confusing hectometer with hectare — the hectometer is a unit of length, the hectare is a unit of area (1 hectare = 1 hm²).
Educational Tips
A football field is roughly 1 hectometer long — use this as a mental benchmark for 100 meters.
About Sun's Radius (R☉)
Definition
The solar radius is the radius of the Sun, approximately 6.9634 × 10⁸ meters (about 696,340 km).
Mathematical Relationship
1 R☉ = 6.9634 × 10⁸ m = 696,340 km ≈ 109 × Earth's radius ≈ 0.00465 AU.
Conversion Formula
To convert solar radii to km: multiply by 696,340. To convert solar radii to AU: multiply by 0.00465.
Practical Applications
Describing stellar sizes: Betelgeuse ≈ 700 R☉, Sirius ≈ 1.7 R☉, a white dwarf ≈ 0.01 R☉.
Interesting Facts
You could line up about 109 Earths across the Sun's diameter. The largest known star (UY Scuti) is about 1,700 R☉.
Common Mistakes
Confusing solar radius with solar diameter — the diameter is 2 R☉. Also, stellar catalogs list radius, not diameter.
Educational Tips
The Sun's radius (109 × Earth) gives a sense of scale: you could fit over a million Earths inside the Sun by volume.
