THE NUMBERS, EXPLAINED
How to use this calculator.
Rectangular joint cross-section, without waste. Actual bead shape and material loss may change yield.
Start with your inputs
Enter joint length (m), width (mm), depth (mm), cartridge volume (ml). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Joint length (m) | 10 |
| Width (mm) | 10 |
| Depth (mm) | 10 |
| Cartridge volume (mL) | 300 |
A worked example
With the example inputs above, cartridges is 4. Change the inputs to explore your own scenario.
Putting the example numbers into the formula
Sealant volume (mL)
(10) × (10) × (10) = 1,000
| Result | Example answer |
|---|---|
| Cartridges | 4 |
| Sealant volume (mL) | 1,000 |
How this is calculated
Cartridges
roundUp(a × b × c ÷ d)
Sealant volume (mL)
a × b × c
Symbols and units
- a
- Joint length (m)
- b
- Width (mm)
- c
- Depth (mm)
- d
- Cartridge volume (mL)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
roundUp(x) rounds up to the next whole number. Values within two floating-point rounding units of an integer are treated as that integer.
Assumptions and limits
Rectangular joint cross-section, without waste. Actual bead shape and material loss may change yield.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Cartridges; Sealant volume (mL). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Rectangular joint cross-section, without waste. Actual bead shape and material loss may change yield.
Are my inputs stored or sent to AI?
