Step 1
Measure the inside cavity in centimetres, millimetres or inches. Use the actual intended fill depth.

MIXKIND / THE METHOD
How to use this tool
Rectangle: V = length × width × depth. Cylinder: V = π × (diameter ÷ 2)² × depth. Total = one cavity × count × (1 + allowance ÷ 100).
Worked example
A 10 × 8 × 2 cm cavity has 160 mL of geometric volume. Three cavities need 480 mL. With a user-selected 5% allowance, the plan is 504 mL.
Step 2
Choose a rectangle or circular cylinder, then enter how many identical cavities you will fill.
Step 3
Add your own allowance if required. Review the net volume and extra volume separately.
Does this include objects inside the mold?
No. The model assumes an empty straight-sided cavity. Embedded objects, irregular surfaces and sloping walls require a separately measured displacement or capacity.
Does the extra allowance set a mixing ratio?
No. It increases the planned combined volume only. The A:B ratio and whether it is by mass or volume still come from the product instructions.
MIXKIND / TOOLKIT
Four ways to plan the same project.
01
Mold volume
Calculate rectangular or cylindrical mold cavity volume using inside dimensions, quantity and your chosen extra allowance.
Open tool02
Volume & weight
Convert volume to mass, or mass to volume, using the density you enter from the matching product data.
Open tool03
A:B mix ratio
Split a known total or a known amount of part A using the exact A:B ratio and mass or volume basis specified by your product.
Open tool04
Batch cost
Add up known masses of A and B, your material prices and the number of identical batches. No live prices or currency conversion.
