如何使用「平方码计算器（码、英尺、英寸、米，多个区域，造价）」？How do I use the Square Yards Calculator (Yards, Feet, Inches, Metres, Several Areas, Cost) tool?
在「平方码计算器（码、英尺、英寸、米，多个区域，造价）」中，填写「输入」、「长」、「宽」、「损耗 %」、「每平方码单价（可选）」等参数，结果会随输入实时计算并显示在下方。In the Square Yards Calculator (Yards, Feet, Inches, Metres, Several Areas, Cost): Fill in "Input", "Length", "Width", "Waste %", "Price per square yard (optional)"; results are recalculated instantly as you type.
平方码怎么算？How are square yards calculated?
长（码）× 宽（码）。用英尺量的话：平方英尺 ÷ 9。例如 12 ft × 15 ft = 180 ft² = 20 yd²。Length × width in yards. From feet, divide square feet by 9: 12 ft × 15 ft = 180 ft² = 20 yd².
米怎么换算？How do metres convert?
1 码 = 0.9144 m，1 平方码 ≈ 0.836 m²，1 m² ≈ 1.196 平方码。1 yard = 0.9144 m, 1 square yard ≈ 0.836 m² and 1 m² ≈ 1.196 square yards.
铺地毯要多买多少？How much extra carpet should I buy?
地毯按卷宽裁切，一般多买 10 % 左右用于接缝和修边，房间形状复杂时更多。Carpet comes in fixed-width rolls, so buy about 10 % extra for seams and trimming, more for awkward rooms.
