Hover any row to copy or use as input. Temperature intervals (differences) only - not absolute temperatures.

Privacy First: Your files are processed securely. Whenever possible, processing happens in your browser and files are never stored on our servers.

Convert temperature intervals (ΔT) across 8 scales. Unlike absolute temperature, intervals convert by simple multiplication: 1 ΔK = 1 Δ°C = 9/5 Δ°F = 9/5 Δ°R = 5/4 Δ°Ré = 100/33 Δ°N = 40/21 Δ°Rø = 2/3 Δ°De. All 8 scales shown simultaneously with material reference. 100% browser-based.

How to Use
