  1. Količina: Masa Oznaka: m (mali tiskani m) Osnovna merska enota: gram Oznaka osnovne merske enote: g Tabela merskih enot s predponami: 2.1.3.1

  2. 2.1.3.2 Absolutna napaka je razlika med točno vrednostjo količine in približno vrednostjo veličine. Enačba:ΔX = Xt – Xpr ΔX … absolutna napaka Xt … točna vrednost količine Xpr … približna vrednost količine Primer: Δm = mt – mpr

  3. 2.1.3.3 Relativna napaka je razmerje (ali ulomek) med absolutno napako in točno vrednostjo veličine. Enačba:δX = ΔX/Xt δX … relativna napaka ΔX … absolutna napaka Xt … točna vrednost količine Primer: δm = Δm/mt

  4. 2.1.3.4 Količina: masa oznaka, osnovna merska enota, oznaka osnovne merske enote, absolutna napaka, relativna napaka, predpone: m, k, d, da, c, μ
