About Square Yard
The square yard is 9 square feet (3 ft × 3 ft). It appears in some sports fields, fabric, and older imperial measurements.
About Square Kilometer
The square kilometer is a metric unit equal to one million square meters. It is standard for city sizes, large properties, and regional planning in metric countries.
How to convert square yards to square kilometers
1 square yard is equal to 8.36127360e-7 square kilometer:
1 yd2 = (0.83612736 m² ÷ 1000000 m²) km2 = 8.36127360e-7 km2
Each square yard is defined as 0.83612736 m² and each square kilometer as 1000000 m², so one yd2 equals 0.83612736 ÷ 1000000 km2 = 8.36127360e-7 km2.
Let a(yd2) be the numeric value of the same area measured in Square Yard (yd2), and a(km2) the value in Square Kilometer (km2). Then:
a(km2) = a(yd2) × (0.83612736 / 1000000)
Equivalently, divide by how many yd2 fit into one km2 (m² per km2 divided by m² per yd2):
a(km2) = a(yd2) ÷ 1195990.04630108037964
Or: square kilometer = square yard ÷ 1195990.04630108037964
Examples
Example #1: Convert 20 yd2 to square kilometer
20 yd2 = 20 yd2 × (0.83612736/1000000) km2 = 0.0000167225 km2
20 yd2 = 20 yd2 ÷ 1195990.04630108037964 = 0.0000167225 km2
Example #2: Convert 50 yd2 to square kilometer
50 yd2 = 50 yd2 × (0.83612736/1000000) km2 = 0.0000418064 km2
50 yd2 = 50 yd2 ÷ 1195990.04630108037964 = 0.0000418064 km2
Summary
To convert Square Yard to Square Kilometer, multiply the value in yd2 by the ratio of square meters per yd2 divided by square meters per km2. Equivalently: value_km2 = value_yd2 × (0.83612736 / 1000000). Numerically, 1 yd2 equals 8.3612736e-7 km2.
Relationship context
You are converting between US customary / imperial (Square Yards) and metric (SI) (Square Kilometers). Metric area is decimal from the square meter; US/imperial units use feet, yards, miles, and acres tied to international feet (0.3048 m) and related definitions. The numeric factor used here is 8.361274e-7.
