The maths behind it
This tool uses Packs = ceiling of (room area × (1 + wastage%) ÷ coverage per pack). Every intermediate value is shown on screen, so the result can be checked by hand.
Keep the leftover boards rather than returning them. A plank replaced in two years after a burst pipe will not match a pack bought then.
