What Is a Yard and What Is a Gigameter?
The yard (yd) is an imperial and US customary unit of length equal to 3 feet or 36 inches. Standardized by the 1959 International Yard Agreement, 1 yard is legally defined as exactly 0.9144 meters.
The gigameter (Gm) is an official SI unit of length equal to 109 meters (1,000,000,000 meters, 1,000,000 kilometers, or approximately 621,371 miles / 1.0936 billion yards).
Because 1 yard equals 0.9144 meters and 1 gigameter equals 109 meters, the conversion is exact: 1 yard = 0.9144 ÷ 109 = 9.144 × 10-10 gigameters.
