How to convert chains to X-units
1 chain is equal to 200,750,439,100,000 X-units, and 1 x-unit is equal to 4.981309155 × 10⁻¹⁵ chains. To convert, multiply by the conversion factor:
X-units = chains × 200,750,439,100,000
X-units = chains ÷ 4.981309155 × 10⁻¹⁵Example: convert 1 ch to xu: 1 × 200,750,439,100,000 = 200,750,439,100,000 xu.
