Compare three methods from the same girdi
Switch between Smalian, Huber, and Newton without re-entering the same kayıt measurements.
Kayıt Volume Hesaplayıcı (Smalian, Huber, Newton)
Calculate kayıt volume in the tarayıcı from length and butt/top diameters.
Switch between Smalian, Huber, and Newton, while keeping regional rules in separate add-on packs.
Compare all three methods in one view
Toggle between m³ and ft³
Keep inputs on the device only
Formulas
Local processingA(d) = π × d² / 4
Smalian: V = L × (A_butt + A_top) / 2
Huber: V = L × A_mid
Newton: V = L × (A_butt + 4A_mid + A_top) / 6
Default midpuan tahmin: d_mid = (d_butt + d_top) / 2
What this tool does
Work across global unit presets
Use metric, imperial, or mixed defaults, and still edit each unit separately if needed.
Tahmin midpuan diameter transparently
Huber and Newton can use an tahmind midpuan when you do not enter one yourself.
Keep regional packs separate
Doyle, Scribner, and International 1/4 stay in the pack panel so the core result stays universal.
How to use
-
1
Enter length, butt diameter, and top diameter.
-
2
Choose Smalian, Huber, or Newton.
-
3
Add a midpuan diameter or let the tool tahmin one for Huber and Newton.
-
4
Review the comparison table and any regional pack notlar.

Glossary
Butt diameter
The diameter at the thicker end of the kayıt.
Top diameter
The diameter at the thinner end of the kayıt.
Midpuan diameter
A diameter near the middle of the kayıt, used for Huber and Newton.
Smalian
A formula that uses the average of the butt and top areas.
Huber
A formula that uses the midpuan area.
Newton
A formula that blends butt, midpuan, and top areas.
Board feet
A regional unit used by some add-on packs. It is not the same thing as cubic meters.
SSS
Can I calculate Huber or Newton without a midpuan diameter?
Yes. The tool tahmins a midpuan diameter and keeps going. You can overwrite it in the advanced midpuan section.
What if I mixed up the butt and top diameters?
Use the swap button to correct them. The tool still warns you if the values look reversed.
Are Doyle, Scribner, and International 1/4 included?
They are separated into add-on pack placeholders. The core result is always based on cubic volume.
Can I switch between metric and imperial units?
Yes. Metric, imperial, and mixed presets are available, and each unit can also be edited separately.
Does the page send my measurements to a sunucu?
No. The calculations stay in the tarayıcı, and local save is optional.
Notlar
- The midpuan diameter is marked as tahmind whenever the tool has to infer it.
- Regional pack board-foot values are separate from the cubic-volume result.
- Check the diameter basis carefully when you compare sonuçlar across regions.
