°F = °C × 9/5 + 32
°C = (°F − 32) × 5/9
K = °C + 273.15
°C = K − 273.15
K = (°F + 459.67) × 5/9
°F = K × 9/5 − 459.67

°F = °C × 9/5 + 32 · °C = (°F − 32) × 5/9 · K = °C + 273.15 · °C = K − 273.15 · °F = K × 9/5 − 459.67 · K = (°F + 459.67) × 5/9.
Absolute zero is the lowest possible temperature: 0 K, −273.15 °C, or −459.67 °F. At this temperature, particle motion reaches its minimum. The tool won't prevent you from entering lower values, but they are physically impossible.
