For instance: 47" Inches x 19" Inches = 893 2) Divide the result by 10. For example: 893 / 10 = 89.3 3) Convert to KG (Kilograms) by dividing the answer by 2.2. For example: 89.3 / 2.2 = 40.5 KG REQUIRED GENERAL GUIDELINES FOR 2" GRAVEL DEPTH 60cm / 2ft TANK = 25 kg 80cm / 2.6ft TANK = 30 kg 100cm / 3.3ft TANK = 35 kg 120cm / 4ft TANK = 40 kg These figures are estimates, and you may prefer a thicker or thinner layer of gravel depending on your design preferences.
