def convert_between_temperature_units(
degrees, current_unit, wanted_unit

wanted_unit :/ Колко пари е наградата ако го намеря? Какво ще кажеш за from_units и to_units?

Също, това подреждане на аргументите е в разрез със стиловите правила - сложи ги на един ред със скобите.

Не се грижи за невалидни аргументи. Просто изпусни else-а. В условието пише, че няма да ви даваме невалидни данни. Освен това, да върнеш произволен стринг е лошо поведение в такъв случай. Просто го остави да гръмне или да върне nil.

Идеята ми е помощна функция convert_to_celsius, която винаги да се извиква в началото на convert_between_temperature_units и след това помощна функция convert_from_celsius. Или с 3 помощни функции convert_to_celsius, convert_to_fahrenheit и convert_to_kelvin. Заемам се веднага и след малко качвам нов вариант. Благодаря за забележките :)

Така е доста по-добре :) А какво ще кажеш за идеята да има само 2 функции - вместо convert_to_celsius, convert_to_fahrenheit и convert_to_kelvin да има само convert_to_celsius и convert_from_celsius :) Така ако искаш да добавиш нова мерна единица няма да се налага да добавяш и още функции.
