Knowledge Center
Welcome to the KP Knowledge Center — your free online hub for engineering tools and sensor guides in industrial temperature measurement.
Created for engineers, technicians, and decision-makers, this resource brings together free-to-use temperature and pressure unit converters and expert technical guides on sensor selection, installation, and standards — all in one place.
Use our calculators to convert temperature units (Celsius, Fahrenheit, Kelvin) and pressure units relevant to thermowell specification. Explore detailed resources on sensor types and temperature ranges, thermowell materials for different environments, thermocouple colour codes across international standards, electrical connection diagrams, and Pt100 / thermocouple wiring configurations.
Whether you need quick unit conversions, are selecting the right thermowell for a project, or require reference materials for industrial sensor technology, the KP Knowledge Center is here to support your work.
Calculator for temperature units
KP’s Free Temperature Conversion Tool
Convert between Celsius (°C), Fahrenheit (°F), and Kelvin (K) instantly with this free engineering tool from Kjaerulf Pedersen a/s.
Supports values from absolute zero (–273.15 °C / –459.67 °F / 0 K) upwards, making it ideal for sensor calibration, thermowell specification, and other industrial temperature measurement tasks.
Frequently Asked Questions
Q: How do I convert Celsius to Kelvin?
A: Add 273.15 to the Celsius value. Example: 25 °C = 298.15 K.
Q: How do I convert Fahrenheit to Celsius?
A: Subtract 32, then multiply by 5/9. Example: 77 °F = 25 °C.
Q: What is absolute zero?
A: Absolute zero is the lowest possible temperature, equal to –273.15 °C, –459.67 °F, or 0 K.
Calculator for pressure units
KP’s Free Pressure Unit Conversion Tool
Convert between bar, PSI, mmWS, Pa, KP/cm², inchWS, Torr, and atm instantly with this free engineering tool from Kjærulf Pedersen a/s. Designed for engineers and technicians working with thermowell and temperature sensor specifications — including high-pressure marine and industrial applications rated up to 500 bar. Ideal for ensuring correct process compatibility when working with gases, steam, water, oil, and other media in closed pipelines and containers.
Frequently Asked Questions
Q: How do I convert bar to PSI?
A: Multiply the bar value by 14.5038. Example: 10 bar ≈ 145.04 PSI.
Q: How do I convert mmWS to bar?
A: Divide the mmWS value by 10197. Example: 5000 mmWS ≈ 0.49 bar.
Q: Why is pressure conversion important for thermowells?
A: Selecting the correct thermowell for your application requires knowing process pressures to ensure safe operation and compliance with design limits — especially in high-pressure environments.
