Deci (D) Skilgreining eininga
Deci is a decimal SI unit prefix in the metric system denoting a factor of one tenth. Proposed in 1793 and adopted in 1795, the prefix comes from the Latin term decimus, meaning tenth. Since 1960, the prefix is part of the International System of Units (SI). It is represented by the prefix deci or the symbol d.
Yfirlit
Deciliter (dL) is common in recipes. Many European homes have a deciliter measure for flour, water etc. Its most frequent use, however, is in a non-SI unit, the decibel (dB), used to measure sound intensity relative to a reference and many other ratios.
Dæmi
A compact disc is about 12 centimeters (cm) or 1.2 decimeters (dm).
10 bel (B) = 1 decibel (dB)
1 liter (L) = 10 deciliters (dL)
1 deciliter (dL) = 10 centiliters (cL)
