I was raised with the metric system and I have to agree with your sentiment. Metric lacks convenient human-sized units. Decimeters are maybe acceptable for lengths, but few people use them. I myself often use feet and inches to describe human-sized objects just because they are more convenient. But as soon as I have to do any kind of work with a quantity beyond pure description, I will swap to metric.
