How to convert chains (US survey) to X-units
1 chain (us survey) is equal to 200,750,840,600,000 X-units, and 1 x-unit is equal to 4.981299192 × 10⁻¹⁵ chains (US survey). To convert, multiply by the conversion factor:
X-units = chains (US survey) × 200,750,840,600,000
X-units = chains (US survey) ÷ 4.981299192 × 10⁻¹⁵Example: convert 1 ch (US) to xu: 1 × 200,750,840,600,000 = 200,750,840,600,000 xu.
