Engineering Calculators

Our engineering calculators are designed to support engineers, designers and technical teams with quick, reliable calculations for a range of common applications.

From electrical formulas to unit conversions and thermal calculations, these tools help simplify complex tasks and provide clear, accurate results to support your design process.

Whether you are selecting components, checking operating conditions or validating calculations, the tools below are intended to save time and improve confidence in your decisions.

Ohm's Law Calculator

Calculate voltage, current, resistance and power using Ohm’s Law by entering any two known values.

Heat Sink Size & Power Resistor Rating Calculators

Estimate the required heat sink thermal resistance or determine the maximum power a resistor can safely dissipate.

PPM to % Converter

Convert between parts per million (PPM) and percentage values quickly and accurately.

Inrush Current Limiter Calculator

Estimate the required heat sink thermal resistance or determine the maximum power a resistor can safely dissipate.

Pressure Unit Converter

Convert pressure values between Bar, PSI, millibar, atmosphere, Pascal and Torr.

Temperature Unit Converter

Convert temperature values between Celsius (°C), Fahrenheit (°F) and Kelvin (K).

Capacitance Conversion Calculator

Convert capacitance values between pF, nF, µF and F quickly and accurately.

Each calculator has been developed to provide straightforward, easy-to-use inputs with clear outputs, helping you compare values and assess performance quickly.



While these tools provide a useful starting point, we recognise that some applications require more detailed consideration. If you need further guidance, our team is available to assist with product selection and technical queries, helping ensure the most suitable solution for your requirements.
