    uc = {'mm': 0.001, 'cm': 0.01, 'm': 1.0, 'km': 1000.}
    return value * uc[unit_from]/uc[unit_to]


print('%.2f' % (unit_converter(1, 'km', 'm')))
print('%.2f' % (unit_converter(1, 'm', 'cm')))
print('%.2f' % (unit_converter(1, 'cm', 'mm')))
print('%.2f' % (unit_converter(1, 'm', 'mm')))
print('%.2f' % (unit_converter(100, 'm', 'km')))
