Yards to Kilometers (yd → km) – Converter & Distance Scale Guide
1. Core Idea
Translate yard-based distances (common in US contexts) to kilometers (SI). Exact base: 1 yard = 0.9144 m; therefore 1 yard = 0.0009144 km. The tool routes through meters internally for precision.
2. Formulas
km = yd × 0.0009144yd = km ÷ 0.0009144 (≈ km × 1093.6133)- Also: 1 mi = 1760 yd = 1.609344 km (consistency check)
3. Quick Values
- 1 yd ≈ 0.0009144 km
- 10 yd ≈ 0.009144 km
- 100 yd ≈ 0.09144 km
- 220 yd (1 furlong) ≈ 0.20117 km
- 440 yd (¼ mile) ≈ 0.40234 km
- 1760 yd (1 mile) = 1.609344 km
4. Worked Example
Convert 3500 yd to km.
km = 3500 × 0.0009144 = 3.2004 km (≈ 3.20 km to 3 sig figs).
5. Uses
- Converting sports track splits (yards) to metric reporting.
- Mapping & GIS data standardization.
- Logistics / navigation distance planning across mixed unit sources.
6. Accuracy & Tips
- Retain 5+ sig figs for cumulative route sums.
- A quick mental shortcut: yd ÷ 1100 ≈ km (close for rough estimation).
- Use miles as an intermediate only if mentally easier: yd ÷ 1760 → mi × 1.609344 → km.
