Units explained
Chain
A chain is an Imperial unit of length equal to 66 feet (20.1168 m), or exactly 4 rods or 100 links. It is the central unit in the Gunter chain-based land-survey system.
Defined by Edmund Gunter in 1620 specifically to make land-area arithmetic easy: 10 square chains = 1 acre exactly. The 66-foot length and 100-link subdivision were chosen so chain measurements could be added decimally.
Chains are the fundamental unit of legacy US public land surveys (the entire US township-and-range system uses chains). Modern survey work generally uses meters or feet, but legacy deeds remain in chains.
Invented by Edmund Gunter in 1620; standardised throughout English and American land survey; became exact via the 1959 International Yard and Pound Agreement.
Kiloyard
A kiloyard is an Imperial unit of length equal to 1,000 yards (914.4 m). It is rarely used in everyday measurement but appears in some technical and military contexts.
The kiloyard combines the metric-style prefix kilo- (Greek chilioi, thousand) with the yard. Standardised via the 1959 International Yard and Pound Agreement.
Kiloyards appear in some artillery and military range specifications, sport-shooting long-range competitions, and certain industrial applications. Less common than the mile for most distances.
Modern usage; standardised through the 1959 International Yard and Pound Agreement.

Step-by-step: convert chains to kiloyards
- Write down the value in chains (ch).
- Multiply that value by the factor 0.022.
- The product is the equivalent value in kiloyards (kyd).
- To reverse, multiply the kiloyard value by 45.4545454545.
Worked examples
Example 1 — Convert 1 ch to kyd:
1 × 0.022 = 0.022 kyd
Example 2 — Convert 100 ch to kyd:
100 × 0.022 = 2.2 kyd
