How far is the storm? How close is lightning? Is the storm looming or is it moving away? Surely everyone has asked themselves such questions. That is why we have created a lightning distance calculator with which you can easily check it.

With this calculator you can calculate the HB hardness or the hardness of metals based on the Brinell hardness test.

Using this calculator, you can calculate the total volume of the solution after dilution and the volume of solvent added during dilution.

With this calculator you will calculate the voltage drops for single-phase and three-phase AC circuits calculated from active power. You will also calculate cable length, conductor diameter, conductor cross-sectional area, phase or line voltage or active power.
