How to Convert Centihenry to Attohenry

Converting Centihenry (cH) to Attohenry (aH) is a core calculation in Inductance, which measures the tendency of an electrical conductor to oppose changes in current by inducing an electromotive force. Both units reside within the International System of Units (SI) and share an identical physical dimension vector ([M L² T⁻² I⁻²]), separated strictly by a decimal order-of-magnitude factor (10^16). Because this shift involves integer powers of 10, the conversion is mathematically exact and free from decimal rounding or irrational fractional loss. Exactly 1 Centihenry equals 1 × 10¹⁶ Attohenry.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (henry (H)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 cH = 0.01 henry (H)

2. Target SI Bridge (k_target):1 aH = 1 × 10⁻¹⁸ henry (H)

Step-by-step substitution for Centihenry → Attohenry:V(aH) = V(cH) × ( 0.01 / 1 × 10⁻¹⁸ ) = V(cH) × 1 × 10¹⁶

Mathematical FormulaValue in Attohenry = Value in Centihenry × 1 × 10¹⁶Direct computational formula applied for standard conversion.

Worked Example

To convert 120 Centihenry (cH) to Attohenry (aH): multiply 120 by 1 × 10¹⁶ to get 1.2 × 10¹⁸ aH. At an industrial engineering scale, 480 cH converts to 4.8 × 10¹⁸ aH.

Inverse check: 1 aH = 1 × 10⁻¹⁶ cH.
