Challenge 135 - Temperature Conversion

Write a program that takes a temperature input in celsius and converts it to Fahrenheit and Kelvin. Return the converted temperature values in a tuple.

The formula to calculate the temperature in Fahrenheit from Celsius is:

F = C*9/5 +32

The formula to calculate the temperature in Kelvin from Celsius is:

K = C + 273.15

Examples

temp_conversion(0) ➞ (32, 273.15)
# 0°C is equal to 32°F and 273.15 K.

temp_conversion(100) ➞ (212, 373.15)

temp_conversion(-10) ➞ (14, 263.15)

temp_conversion(300.4) ➞ (572.72, 573.55)

Notes

• Return calculated temperatures up to two decimal places.
• Return "Invalid" if K is less than 0.
