+## temperature_conv
+
+### Instructions
+
+Write two functions to transform values of temperatures from celcius to fahrenheit and the other way arraound:
+
+### Expected funcions
+
+```rust
+fn fahrenheit_to_celsius(f: f64) -> f64 {
+}
+
+fn celsius_to_fahrenheit(c: f64) -> f64 {
+}
+```
+
+### Usage
+
+```rust
+use temperature_conv::*;
+
+
+fn main() {
+	println!("{} F = {} C", -459.67, fahrenheit_to_celsius(-459.67));
+	println!("{} C = {} F", 0.0, celsius_to_fahrenheit(0.0));
+}
+```
