+# The Temperature
+
+> **[INCOMING — Mission Control, Earth]**
+>
+> Cadet, half the world reads temperature in Fahrenheit, the other
+> half in Celsius. Build a converter.
+>
+> Formula: `C = (F - 32) * 5 / 9`
+>
+> Implement `f_to_c(f)` that returns a string of the form:
+>
+> ```
+> <F>°F = <C>°C
+> ```
+>
+> Where `<C>` is rounded to one decimal place using `:.1f`. Convert
+> the input with `float()` first so the output is consistent for
+> int and float inputs.
+>
+> Examples:
+>
+> - `f_to_c(32)` → `"32.0°F = 0.0°C"`
+> - `f_to_c(212)` → `"212.0°F = 100.0°C"`
+> - `f_to_c(98.6)` → `"98.6°F = 37.0°C"`
+>
+> [END TRANSMISSION]
+
+## Your Task
+
+In `starter/starter.py`, convert `f` to float, compute Celsius,
+return the formatted string.
+
+## Objectives
+
+- All three examples produce the exact expected string
+- Works for any numeric F input
