Kelvin (difference) quick reference
| Kelvin (difference) | Degree Celsius (difference) | Degree Fahrenheit (difference) | Degree Rankine (difference) |
|---|---|---|---|
| 1 ΔK | = 1 Δ°C | = 1.8 Δ°F | = 1.8 Δ°R |
| 10 ΔK | = 10 Δ°C | = 18 Δ°F | = 18 Δ°R |
| 100 ΔK | = 100 Δ°C | = 180 Δ°F | = 180 Δ°R |
| 1000 ΔK | = 1000 Δ°C | = 1800 Δ°F | = 1800 Δ°R |
Where the kelvin (difference) fits
The next smaller temperature interval unit is the degree Fahrenheit (difference) (Δ°F). 1 ΔK = 1.8 Δ°F, and 1 Δ°F ≈ 0.5555555556 ΔK.
