Lorentz Factor Calculator
Enter velocity as a fraction of the speed of light (v/c, between 0 and 1) to compute gamma.
Summary
Gamma (Γ, γ) is the third letter of the Greek alphabet and, unlike alpha or beta, its uppercase form has a shape of its own instead of borrowing from the Latin alphabet. Lowercase gamma commonly labels the Lorentz factor in relativity, a photon energy in gamma radiation, an options risk measure in finance, or a shape parameter in statistics, while uppercase Gamma names the gamma function in calculus. This tool gives a one-click copy of both cases plus every code format: Unicode codepoint, HTML entity, LaTeX command, and keyboard shortcuts.
How it works
- Click the large gamma symbol to copy the lowercase letter to your clipboard.
- Switch between lowercase (γ) and uppercase (Γ) with the toggle above it.
- Click any row in the formats list to copy that exact string: Unicode, HTML entity, or LaTeX.
- Enter a velocity as a fraction of the speed of light in the calculator to compute the Lorentz factor.
Use cases
- Write the Lorentz factor in special relativity, such as gamma in E = gamma * m * c squared.
- Reference gamma radiation or a gamma ray in a physics or radiology note.
- Insert the gamma function into a math paper, such as Gamma(n) = (n-1)! for positive integers.
- Label an option's gamma, the second-order sensitivity of delta to the underlying price, in a trading note.
- Set the shape parameter of a gamma distribution in a statistics or reliability model.
- Add the correct HTML entity or LaTeX command instead of typing a lookalike character.
