About this angle: degrees, radians and gradians
Convert degrees, radians and gradians; show reduced π fractions and sin, cos and tan Computes exact algebraic and numerical metrics directly in your browser using IEEE 754 precision without round-trip latency.
Formula & calculation mechanics
The execution engine processes input tokens and applies transformations in the browser sandbox. Specifically, Choose a unit and enter a decimal, or select 30°, 45° or 60°. Unit changes keep the number and reinterpret it. radians=degrees×π/180; degrees=radians×180/π; 200 gon=180°.
Worked numerical calculation
Scenario: Example: 30° = π/6 rad = 33.3333333333 gon; sin=0.5, cos≈0.866025403784, tan≈0.57735026919.
Sample input:
Processing: Choose a unit and enter a decimal, or select 30°, 45° or 60°. Decimal degrees, gradians and π coefficients give an exact reduced fraction using integer arithmetic. Decimal radians are approximate: no exact π fraction is inferred. Trigonometric values use floating point; tan is undefined at exact odd multiples of π/2.
Illustrative output:
Domain range & precision boundaries
Form limits: at most 64 characters, |input| ≤ 10¹², scientific exponent −100…100. Use a decimal point, no unit suffix. Numerical results show up to 12 significant digits. The legacy JSON panel retains its previous numeric range.
Calculations in Angle: degrees, radians and gradians use standard IEEE 754 precision or exact rational models. Verify significant accounting or tax figures with authoritative references.
