One meter is equal to 1.0936 yards, so in order to convert 300 meters into yards, simply multiply by 1.0936 to get 328.084 yards. Because the metric system is based on a 10 multiplier system, it is easy to use this simple conversion to calculate other metric lengths in terms of yards. For instance, 328.084 yards is equal to 3,000 decimeters, 30,000 centimeters and 0.3 kilometers.
Converting English units such as yards into metric units is more difficult because English units aren't based on common multipliers. You need a conversion table in order to work out the different ratios between units. For example, there are 12 inches in a yard but 1,760 yards in a mile.
