Metrički i imperijalni unos
Unesite dimenzije u metričkim ili imperijalnim jedinicama i usporedite rezultate na jednom zaslonu.
Kalkulator volumena balvana
Izračunajte volumen trupca prema duljini, promjeru i metodi mjerenja, a zatim usporedite različite pristupe.
Koristan je za brze procjene na terenu i za usporedbu metoda između timova i tržišta.

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 midpoint estimate: d_mid = (d_butt + d_top) / 2

How to use
-
1
Enter length, butt diameter, and top diameter.
-
2
Choose Smalian, Huber, or Newton.
-
3
Add a midpoint diameter or let the tool estimate one for Huber and Newton.
-
4
Review the comparison table and any regional pack notes.
Primjeri
Typical metric log
Ulaz / IzlazUlaz: Length 4 m, butt diameter 28 cm, top diameter 18 cm, count 20, method Smalian
Izlaz: About 0.174 m³ per log, about 3.48 m³ total
Huber with midpoint
Ulaz / IzlazUlaz: Length 4 m, butt diameter 28 cm, top diameter 18 cm, midpoint diameter 23 cm, method Huber
Izlaz: About 0.166 m³ per log, about 3.32 m³ total
Imperial check
Ulaz / IzlazUlaz: Length 16 ft, butt diameter 11 in, top diameter 7 in, count 10, method Newton
Izlaz: About 7.18 ft³ per log, about 71.8 ft³ total
Glossary
Butt diameter
The diameter at the thicker end of the log.
Top diameter
The diameter at the thinner end of the log.
Midpoint diameter
A diameter near the middle of the log, used for Huber and Newton.
Smalian
A formula that uses the average of the butt and top areas.
Huber
A formula that uses the midpoint area.
Newton
A formula that blends butt, midpoint, and top areas.
Board feet
A regional unit used by some add-on packs. It is not the same thing as cubic meters.
Česta pitanja
Can I calculate Huber or Newton without a midpoint diameter?
Yes. The tool estimates a midpoint diameter and keeps going. You can overwrite it in the advanced midpoint 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 server?
No. The calculations stay in the browser, and local save is optional.
Važne napomene
- The midpoint diameter is marked as estimated 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 results across regions.
