🐠 鱼缸容积计算器Aquarium Volume Calculator
计算长方体、圆柱、弧面（弓形前脸）、六角形和转角扇形鱼缸的水量（升、美制加仑、英制加仑）和水重，可扣除玻璃厚度和水面到缸口的距离。Work out how much water an aquarium holds — rectangular, cylindrical, bow-front, hexagonal or corner (quarter-circle) — in litres, US and UK gallons, with the weight of the water, optionally allowing for glass thickness and the gap below the rim.

如何使用「鱼缸容积计算器」？How do I use the Aquarium Volume Calculator tool?
在「鱼缸容积计算器」中，填写「单位」、「形状」、「长度」、「宽度（深度）」、「弧面凸出量」等参数，结果会随输入实时计算并显示在下方。In the Aquarium Volume Calculator: Fill in "Units", "Shape", "Length", "Width (front to back)", "Bow depth"; results are recalculated instantly as you type.
鱼缸容积怎么算？How is aquarium volume calculated?
容积 = 底面积 × 水深。长方体：长 × 宽；圆柱：π × 直径² ÷ 4；正六角形：3√3 ÷ 2 × 边长²；转角扇形：π × 半径² ÷ 4；弧面前脸 = 长方形部分 + 前面的圆弓形（由长度和凸出量求出）。1 升 = 1,000 立方厘米。例如 60 × 30 × 36 厘米的缸约 64.8 升。Volume = base area × water depth. Rectangular: length × width; cylinder: π × diameter² ÷ 4; hexagon: 3√3 ÷ 2 × side²; corner tank: π × radius² ÷ 4; bow-front = the rectangle plus the circular segment at the front (found from the length and bow depth). 1 litre = 1,000 cm³, so a 60 × 30 × 36 cm tank holds about 64.8 litres.
玻璃厚度和水位怎么处理？How are glass and water level handled?
长方体和圆柱可以填写玻璃厚度：长、宽（或直径）各减去两层玻璃，高度减去底板一层；再减去水面到缸口的距离，得到实际水量。For rectangular and cylindrical tanks you can enter the glass thickness: two panes come off the length and width (or diameter) and one off the height for the base. The gap below the rim is then subtracted to give the actual water volume.
水有多重？How heavy is the water?
淡水约 1 千克/升（1 美制加仑约 8.34 磅），海水约 1.025 千克/升。再加上玻璃、底砂和石头，放置鱼缸前请确认柜子和楼板的承重。Fresh water weighs about 1 kg per litre (about 8.34 lb per US gallon) and seawater about 1.025 kg per litre. Add the glass, gravel and rock, and check that your stand and floor can carry it.
