Here's how to convert 801 Celsius to Fahrenheit and Kelvin:

Celsius to Fahrenheit:

* Formula: °F = (°C × 9/5) + 32

* Calculation: (°F = (801 × 9/5) + 32

* Result: 1474 °F

Celsius to Kelvin:

* Formula: K = °C + 273.15

* Calculation: K = 801 + 273.15

* Result: 1074.15 K

Therefore:

* NaCl melts at 1474 °F.

* NaCl melts at 1074.15 K.
