This physics time to frequency calculator that converts between time period and frequency. This conversion is crucial in physics, engineering, and signal processing.
The calculator uses the inverse relationship between period and frequency, allowing quick transformations between these two wave characteristics.
Our time period to frequency converter helps us understand how often an event occurs (frequency) when we know the duration of one complete cycle (period), or vice versa. This tool is essential for anyone working with waves, oscillations, and periodic phenomena.

- Wave Frequency (f): Used the formula
f = 1 / TFor example, when T = 1 second, f = 1 / 1 = 1 Hz - Angular Frequency (ω) in radians: Used the formula
ω = 2π / TFor example, when T = 1 second, ω = 2π / 1 ≈ 6.28318 rad/s - Angular Frequency (ω) in degrees: Used the formula
ω = 360 / TFor example, when T = 1 second, ω = 360 / 1 = 360°/s

Period to Frequency Calculation Formula
The core principle behind the calculation frequency to period is the reciprocal relationship between period and frequency.
The formulas used are:
- Wave or Rotational Frequency:
f = 1 / TWhere:- f is the frequency (typically measured in Hertz, Hz)
- T is the time period (usually measured in seconds)
- Angular Frequency:
ω = 2 · π / T (in radians) ω = 360 / T (in degrees)Where:- ω is the angular frequency
- π is the mathematical constant Pi (approximately 3.14159)
- T is the time period
How do you convert time constant to frequency?
Converting a time constant to frequency involves understanding their relationship and applying the appropriate formula.
While the time constant is not identical to the period, they are related, and we can use a similar approach for conversion.
To convert a time constant to frequency:
- Understand the time constant: In many systems, particularly in electrical engineering and signal processing, the time constant (τ) represents the time for a system to reach about 63.2% of its final value in response to a step input.
- Relate time constant to period: For many systems, the period (T) of oscillation relates to the time constant (τ) by:
T = 2π · τ - Apply the frequency formula: Once you have the period, use the standard frequency formula:
f = 1 / T - Combine the steps: Putting it all together:
f = 1 / (2π · τ)
This formula allows direct conversion from time constant to frequency.
The exact relationship between time constant and frequency can vary by system or context. Some variations include:
- For RC circuits: f = 1 / (2π · RC)
- For RL circuits: f = R / (2π · L)
Where R is resistance, C is capacitance, and L is inductance.
