Physics Calculators

Tools for converting between physical quantities using exact formulas from classical physics and electromagnetic theory.

Frequency to Period

Convert frequency to period using T = 1/f. Supports Hz, kHz, MHz, GHz, THz to seconds, milliseconds, microseconds, nanoseconds.

Formula: T = 1 / f

Frequency to Wavelength

Convert frequency to wavelength in vacuum using λ = c/f (c = 299,792,458 m/s). Supports Hz to meters, centimeters, millimeters, micrometers, nanometers.

Formula: λ = c / f

Wavelength to Frequency

Convert wavelength to frequency using f = c/λ. Supports meters, centimeters, millimeters, micrometers, nanometers to Hz, kHz, MHz, GHz, THz.

Formula: f = c / λ

About These Calculators

Unlike proportional unit conversions (e.g., meters to feet), these physics transformations use inverse relationships. A higher frequency means a shorter period and a shorter wavelength.

All calculations use the SI-defined speed of light: c = 299,792,458 m/s (exact).

All physics calculations on CoolConversion use constants defined by internationally recognised standards bodies (SI/BIPM).
