18 Celsius to Fahrenheit (18°C to °F)
18°C = 64.4°F
Formula
°F = (°C × 9/5) + 32
°F = (°C × 9/5) + 32 °F = (18 × 9/5) + 32 °F = 32.4 + 32 °F = 64.4
Direction locked to °C → °F
Formula & steps
°F = (°C × 9/5) + 32
°F = (°C × 9/5) + 32 °F = (18 × 9/5) + 32 °F = 32.4 + 32 °F = 64.4

Where 18°C shows up
18°C is 64.4°F: (18 × 9/5) + 32 = 32.4 + 32 = 64.4. It is a cool indoor setpoint or a mild outdoor reading in temperate weather.
Compared with 20°C (68°F), 18°C is 2°C / 3.6°F cooler. Night-setback thermostats and unheated rooms often land near this range.
