ʻO ka mānoanoa o ka uhi ʻana i ke kila kila
E hoʻohana i kēia mau pilina no ke koho ʻana i ka mānoanoa o ka uhi ʻana mai ke kaumaha o ka uhi [nui]:
1.00 oz/ft2 ka paona uhi ʻana = 1.68 mils ka mānoanoa o ka uhi ʻana,
7.14 g/m2 uhi nuipa = 1.00 µm mānoanoa uhi.
E hoʻohana i ka pilina ma lalo nei e hoʻololi i ke kaumaha o ka uhi ʻana i ka nui o ka uhi ʻana:
