Calculate Wire weight: 0.5mm, mm2, 30m, g, copper


This can calculate the wire weight (m) knowing its diameter (d) or cross section area (A) and the length (ℓ). It can also calculate the diameter and cross section area knowing the weight and length. You can also calculate the conductor length knowing its diameter or cross section area and the weight. Works for copper, aluminium and iron.
Diameter to cross section area: A=π•d²/4     Cross section area to diameter: d=2•√A/π     Wire weight (mass) knowing the density and volume: m=ρ•V     Wire volume knowing the diameter and length: V=(πd²ℓ)/4

Wire materials:

Copper: the best conductor of all non-precious metals. Its chemical symbol is Cu. Typical conductivity of a copper wire is about 57 MS/m and the resistivity about 17.54 nΩ⋅m. Density: 8.96 g/cm³. Linear thermal expansion: 16.7um/(m⋅K).
Aluminium: cheaper and lighter than copper, good conductivity. Its chemical symbol is Al. Typical conductivity of an aluminium wire is about 35.5 MS/m and the resistivity about 28.2 nΩ⋅m. Density: 2.70 g/cm³. Linear thermal expansion: 23.1um/(m⋅K).
Iron: very cheap, works as both a conductor and a structural part. Its chemical symbol is Fe. Typical conductivity of iron is about 10.3 MS/m and the resistivity about 97.1 nΩ⋅m. Density: 7.874 g/cm³. Linear thermal expansion: 11.8um/(m⋅K).

Wire weight formula says:

•A 0.5 mm (millimeters) diameter wire has a 0.1963495408494 mm² (square millimeters) cross section area. If such copper (Cu) wire is 30m (meters) long, its weight is 52.77875658031g (grams).
•If a 30m (meters) long copper (Cu) wire weighs 52.77875658031g (grams), its diameter is 0.5 mm (millimeters) and its cross section area is 0.1963495408494 mm² (square millimeters).
•A 0.5 mm (millimeters) diameter / 0.1963495408494 mm² (square millimeters) cross section area copper (Cu) wire that weighs 52.77875658031g (grams) is 30m (meters) long.
