Temperature Conversion Calculator

Easily Convert Between Fahrenheit and Celsius
Use TUTCO Farnam’s Temperature Conversion Calculator to quickly and accurately convert temperatures between Fahrenheit and Celsius. Whether you're working with process heating specs, lab data, or international temperature standards, this tool makes it easy to get the equivalent value in either unit. Just enter your known temperature and let the calculator do the work—perfect for engineers, designers, and anyone working with thermal systems.

Three Phase Unit Calculator

Calculate Wattage, Voltage, or Line Current for Three-Phase Systems
TUTCO Farnam’s Three Phase Unit Calculator helps you determine the missing value—wattage, voltage, or line current—based on the two known values in your three-phase power system. Ideal for engineers and technicians designing or troubleshooting industrial heating equipment, this tool simplifies complex electrical calculations, saving time and ensuring accuracy in your process heating setup.

Single Phase Unit Calculator

Quickly Solve for Wattage, Voltage, or Current in Single-Phase Systems
Use TUTCO Farnam’s Single Phase Unit Calculator to find the missing value in your single-phase electrical system—whether it’s wattage, voltage, or current. Simply enter any two known values, and the calculator will instantly provide the third. This tool is perfect for professionals working with electric heaters or other equipment requiring accurate single-phase power calculations.

Power Flow Temperature Calculator

Determine Power, Airflow, or Temperature Rise in Your Heating System
TUTCO Farnam’s Power Flow Temperature Calculator is designed to help you calculate one of three critical values in your air heating application: power (watts), airflow (SCFM), or temperature rise (ΔT in °F). Using the formula Watts = SCFM × ΔT / 3, simply enter any two known values to solve for the third. This tool is especially useful for engineers sizing heaters or optimizing airflow in thermal systems.

OHMS Law Calculator

Solve for Amps, Volts, Watts, or Resistance with Ohm’s Law
TUTCO Farnam’s Ohm’s Law Calculator makes it easy to determine electrical values in your circuit by calculating any two unknowns when you enter the other two. Whether you're working with amps (current), volts (voltage), watts (power), or ohms (resistance), this tool helps ensure safe and accurate electrical design—especially useful when specifying or troubleshooting electric heaters and control systems.

Heat Transfer Through Convection Calculator

Calculate Heat Transfer in Convection-Based Systems
Use TUTCO Farnam’s Heat Transfer Through Convection Calculator to determine one of five key values—heat transfer rate (Q), density (ρ), volume flow rate (V), specific heat (Cp), or temperature differential (ΔT)—by entering the other four. Based on the equation Q = ρ × V × Cp × (Tₐ - Tᵦ), this tool is ideal for engineers designing or optimizing forced-air heating systems where convection is the primary heat transfer method.

Standard Flow Calculator

Convert Actual CFM to Standard CFM (SCFM) for Accurate Airflow Measurement
TUTCO Farnam’s Standard Flow Calculator helps you determine the Standard Cubic Feet per Minute (SCFM) based on actual flow conditions—accounting for pressure (PSI), temperature (°F), and actual CFM. By entering any three of these values, the calculator uses the industry-standard formula to give you an accurate SCFM reading. This is essential for designing and evaluating air-based heating systems where consistent airflow measurement is critical.

Pressure Conversion Calculator

Easily Convert Between PSI and Bar
Use TUTCO Farnam’s Pressure Conversion Calculator to quickly switch between PSI (pounds per square inch) and Bar, two common units of pressure measurement in industrial and process heating systems. Just enter one value, and the calculator will instantly provide the equivalent in the other unit using the standard conversion factor. It’s a simple but essential tool for engineers working across international standards or with diverse equipment specifications.
