| 1 | Formula Penukaran Wire-Wire-Wire-Wire dan Panjang Enameled Copepr Wire | L/kg | L1 = 143m/(D*D) |
| 2 | Formula Penukaran Kawat dan Panjang Penukaran Rectangular Wire | g/l | Z = (T*W-0.2146*T2)*8900*1000/1000000 |
| 3 | Kawasan keratan rentas segi empat tepat | mm2 | S = T*W-0.2146*T2 |
| 4 | Formula penukaran berat dan panjang litz | L/kg | L2 = 274 / (d*d*2*helai) |
| 5 | Rintangan dawai segi empat tepat | Ω/l | R = r*l1/s |
| 6 | Formula 1: Rintangan Kawat Litz | Ω/l | R20 = RT × α × 103/L3 |
| 7 | Formula 2: Rintangan Kawat Litz | Ω/l | R2 (Ω/km) ≦ R × 1.03 ÷ S × pada × 1000 |
