Relay lifetime online calculator

TechOverflow calculators:
You can enter values with SI suffixes like 12.2m (equivalent to 0.012) or 14k (14000) or 32u (0.000032).
The results are calculated while you type and shown directly below the calculator, so there is no need to press return or click on a Calculate button.

*Note:*A cycle is typically defined as switching the relay on and switching it off again, i.e. one cycle consists of two switch actions (on + off).

In case you know how many seconds between cycles:

s
cycles
$$N_{\text{predicted}} = N_{\text{nominal}} \cdot \text{Seconds between cycles}$$

In case you know how many relay cyclesper second**:

Hz
cycles
$$N_{\text{predicted}} = \frac{N_{\text{nominal}}}{\text{Cycles per second}}$$
