    16 is the ninth composite number, and a square number: 42 = 4 × 4 (the first non-unitary fourth-power prime of the form p4). It is the smallest number with exactly five divisors, its proper divisors being 1, 2, 4 and 8.

    Sixteen is the only integer that equals mn and nm, for some unequal integers m and n ( ,  , or vice versa).[1] It has this property because  . It is also equal to 32 (see tetration).

    The aliquot sum of 16 is 15, within an aliquot sequence of four composite members (16, 15, 9, 4, 3, 1, 0) that belong to the prime 3-aliquot tree.

    16 is the only number that can be both the perimeter and area of the same square, due to   being equal to

    As a unit of measurement

    edit

    A low power of two, 16 was used in weighing light objects in several cultures. The British have 16 ounces in one pound; the Chinese used to have 16 liangs in one jin. In old days[vague], weighing was done with a beam balance to make equal splits. It would be easier to split a heap of grains into sixteen equal parts through successive divisions than to split into ten parts. Chinese Taoists did finger computation on the trigrams and hexagrams by counting the finger tips and joints of the fingers with the tip of the thumb. Each hand can count up to 16 in such manner. The Chinese abacus uses two upper beads to represent the 5s and 5 lower beads to represent the 1s, the 7 beads can represent a hexadecimal digit from 0 to 15 in each column.
