    A quire of paper is a measure of paper quantity. The usual meaning is 25 sheets of the same size and quality: 1 ⁄ 20 of a ream of 500 sheets. Quires of 25 sheets are often used for machine-made paper, while quires of 24 sheets are often used for handmade or specialised paper of 480-sheet reams.

    The log-normal distribution is often used to approximate the particle size distribution of aerosols, aquatic particles and pulverized material. The Weibull distribution or Rosin–Rammler distribution is a useful distribution for representing particle size distributions generated by grinding, milling and crushing operations.

    Size can also be measured in terms of mass, especially when assuming a density range. This animation gives a sense of the scale of some of the known objects in our universe. In mathematical terms, "size is a concept abstracted from the process of measuring by comparing a longer to a shorter". [1]
