Hello everyone, in unit conversion, some people make mistakes and confuse the unit conversion from time to time, causing unnecessary troubles.
So what I share with you today is a unit conversion applet made with python's math and time modules (the current unit is not comprehensive, there are only some commonly used units), which includes common unit conversions for length, area, weight, and temperature. This program may have some bugs, and I hope you guys don't like it if you don't like it.
On the source code:
import time
import math
time.sleep(0.5)
print('----------Welcome to the unit conversion system---------')
time.sleep(1)
print()
print( '1. Length conversion')
print('2. Area conversion')
print('3. Weight conversion')
print('4. Temperature conversion')
print()
time.sleep(1)
