How to Convert Foot to Sun's Radius
To convert feet to meters: multiply by 0.3048. To convert meters to feet: multiply by 3.28084.
1 ft = 12 in = 0.3048 m = 1/3 yd = 30.48 cm.
For example, 1 Foot (ft) = 4.377172e-10 Sun's Radius (R☉).

About Foot (ft)
Definition
The foot is a unit of length equal to 12 inches or exactly 0.3048 meters.
Mathematical Relationship
1 ft = 12 in = 0.3048 m = 1/3 yd = 30.48 cm.
Conversion Formula
To convert feet to meters: multiply by 0.3048. To convert meters to feet: multiply by 3.28084.
Practical Applications
Building plans, ceiling heights, personal height, pool depth, altitude in aviation, and real estate listings.
Interesting Facts
The international foot (0.3048 m exactly) differs slightly from the US survey foot (1200/3937 m), which was deprecated in 2023.
Common Mistakes
Confusing the foot with 30 cm (it's 30.48 cm). Also, forgetting that 5′10″ is not 5.10 feet — it's 5 feet 10 inches = 5.833 feet.
Educational Tips
There are 3 feet in a yard and 5,280 feet in a mile. A 6-foot person is about 1.83 meters tall.
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.
