Oven Thermostat to Celsius Conversion: Complete Temperature Chart

As an experienced home cook, I've learned that recipes often list oven temperatures in Celsius or by thermostat number. This guide provides a precise conversion chart based on standard oven calibrations, helping you match the right heat level every time—whether it's a gentle warm or blazing hot bake.

Warm Oven

• Thermostat 1 = 30°C
• Thermostat 2 = 60°C

Mild Oven

• Thermostat 3 = 90°C
• Thermostat 4 = 120°C

Medium Oven

• Thermostat 5 = 150°C
• Thermostat 6 = 180°C

Hot Oven

• Thermostat 7 = 210°C

Very Hot Oven

• Thermostat 8 = 240°C
• Thermostat 9 = 270°C

Extra Hot Oven

• Thermostat 10 = 300°C

Quick Conversion Tip

Each thermostat number adds 30°C: multiply the setting by 30 for Celsius (e.g., thermostat 6 = 6 × 30 = 180°C). For the reverse, divide Celsius by 30 (e.g., 120°C ÷ 30 = thermostat 4). This reliable formula ensures perfect results across all recipes.
