Schwarzschild Radius From Mass
Nonrotating uncharged Schwarzschild 2 GM/c²radius; not general spinning horizon radius. Model only, not an ephemeris, measured stellar identity or observational guarantee.
Description
The Schwarzschild radius describes an ideal nonrotating, uncharged mass model.
The Schwarzschild radius describes an ideal nonrotating, uncharged mass model.1
It is a characteristic radius rather than an observed physical surface for every object. Use Schwarzschild Radius From Mass to evaluate the supplied inputs under the model explained below.
When to use Schwarzschild Radius From Mass
Use Schwarzschild Radius From Mass to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Schwarzschild Radius From Mass and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Mass kg using the field table and validation rules below, then run the tool.
- Read Schwarzschild radius meters; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| massKg | Mass kg | number | Required; constraints below |
Enter nonnegative mass in kg. Compute 2GM/c² with G=6.6743e−11 m³/(kg·s²) and c=299792458 m/s, returning m. Zero mass returns zero; rotation, charge and an actual horizon observation are outside this model.
SchwarzschildRadiusM=2×G×massKg/c² Use the field order, units and branch conditions described above.
| Output field | Meaning | Value type |
|---|---|---|
| schwarzschildRadiusMeters | Schwarzschild radius meters | number |

}Limitations and assumptions
It is a characteristic radius rather than an observed physical surface for every object. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
