Calculators

Estimates how long a battery will last based on its capacity and the device's power consumption.

Calculates the air-fuel ratio (AFR), which represents the mass ratio of air to fuel in an internal combustion engine. This ratio is crucial for efficient combustion and emissions control.

Calculates how cold the air feels based on actual air temperature and wind speed.

Calculates the component values (e.g., in L-networks) needed to match impedances for maximum power transfer.

Calculates the change in length, area, or volume of a material due to a change in temperature.

Analyzes circuits with resistors, inductors, and capacitors, calculating impedance and resonant frequency.

Calculates voltage, current, or resistance in an electrical circuit using Ohm's Law (V=IR).

Determines the resistance and tolerance of a resistor based on its colored bands.

Calculates the mean free path of a particle, which is the average distance a particle travels between collisions.

Calculates battery capacity (e.g., in mAh or Wh) based on voltage and charge/discharge characteristics.
