python制作换算表格

怎么用while语做一个1-10cm换算mm，m，inch的程序

s = 1
while s <= 10:
    print(f'{s}厘米={s*10}毫米={s/100}米={format(s/2.54,".7f")}inch')
    s += 1

a = {'cm': 1, "m": 0.1, "mm": 10, "inch": 0.393700787402}
num = int(input())
print("{}cm可以换算成{}m,{}mm,{}inch".format(num, num * a['m'], num * a['mm'], num * a['inch']))
