Measures and weights
Units of measurement in leather
Leather is a natural material and hence not available in rolls like other fabrics. For this reason, the external contours of the animal skin are too irregular. Leather is measured and calculated in square metres, decimetres, square feet (inch: inches), lengthwise or in kilogrammes. When speaking of leather, it is common to use words like weight leather and surface leather while leather laces and leather strips are sold by length.
Leather skin has different qualities within a skin making it impossible to sell the entire surface of the skin. These are sometimes cut in parts with different qualities and each section has corresponding technical terms.
Leather surface measurement
Large skins, such as bovine skins, are measured in square metres (m²). Occasionally, decimetres (dm²) are indicated. A cattle skin usually has 4.5 to 5.5 square metres. There are also larger (up to 6 sqm) and smaller skins. Leather dealers mostly sell complete and half skins. For certain purposes, further sections of the animal skin are sold. Smaller sections are sold reluctantly, leading to higher waste during the cutting process.
For large hides, the measure is usually square metres. However, decimetres are also given.
Full hide - Half hide. The division takes place along the back line.
The conversion factor for the conversion from square metres to square feet is 10,764, from square metres to square inches 1550,003.
2,95 square metres x 10,764 = 31,75 square feet
45 square feet: 10,764 = 4,18 square metres
Leather by weight
Leather according to length
Reptile leather is calculated by length.
The leather thickness is measured in millimetres with special measuring instruments.
