Formula
Variables
- T — Temperature (K)
Worked example
With temperature = 293 K, the calculator gives thermal neutron speed ≈ 2,197.82 m/s; thermal neutron speed ≈ 2.19782 km/s.
Frequently asked questions
What is the thermal neutron speed calculator used for?
Find the typical speed of neutrons in thermal equilibrium at a given temperature. It helps with questions such as “thermal neutron speed”, “neutron moderator speed”, “neutron temperature speed”.
What is the formula for the thermal neutron speed calculation?
Thermal neutron speed (m/s) = √(2 × KB × T / 1.67493e-27). Thermal neutron speed (km/s) = [Thermal neutron speed] / 1000. Here T is temperature (K).
What inputs do I need for the thermal neutron speed calculator?
You need temperature in K. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the thermal neutron speed calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the thermal neutron speed result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
