What Is This Tool?
This tool allows users to convert temperature measurements from the triple point of water unit to kelvin (K). It is useful for transforming an exact fixed point used in temperature calibration into the SI base unit for thermodynamic temperature.
How to Use This Tool?
-
Enter the temperature value in the triple point of water units
-
Select triple point of water as the input unit
-
Choose kelvin [K] as the output unit
-
Click the convert button to get your result in kelvin
-
Use the output for calibration or scientific calculations
Key Features

-
Based on internationally recognized fixed points and definitions
-
Supports temperature calibration and metrology applications
-
Easy to use interface for quick and precise conversions
-
Browser-based tool accessible without installation
Examples
-
1 Triple point of water = 273.16 K
-
2 Triple point of water = 546.32 K (2 × 273.16 K)
Common Use Cases
-
Calibrating thermometers and temperature sensors in standards labs
-
Maintaining and realizing the kelvin unit definition in metrology
-
Verifying temperature-controlled research and industrial equipment
-
Reporting thermodynamic temperature in scientific and engineering contexts
-
Supporting thermodynamic and astrophysical temperature analyses
Tips & Best Practices
-
Ensure purity of water and correct pressure conditions when using triple point measurements
-
Use this fixed point for calibration rather than variable temperature measurement
-
Apply conversions in controlled laboratory and industrial environments only
-
Leverage the tool for standardizing temperature measurements and comparisons
-
Double-check unit selections before conversion to avoid errors
Limitations
-
The triple point of water is a fixed temperature and pressure point, not a variable measurement
-
Conversion accuracy depends on maintaining specified pressure and water purity
-
Not suitable for general temperature measurements outside controlled environments
Frequently Asked Questions
-
What is the triple point of water?
-
It is the unique temperature and pressure at which water's solid, liquid, and vapor phases coexist in thermodynamic equilibrium, used as a fixed temperature reference.
-
How does the kelvin differ from the triple point of water unit?
-
Kelvin is the SI base unit of thermodynamic temperature measured on an absolute scale, whereas the triple point of water represents a precise fixed reference temperature.
-
Can the triple point of water be used as a variable temperature unit?
-
No, it is a fixed point under specific conditions and cannot be varied for different temperatures.
