Kayıt Volume and Load Hesaplayıcı

Calculate kayıt volume from small-end diameter, butt-end diameter, and length, then tahmin load weight from density.

Editable volume rules and density tables make it easier to adapt the page to regional kayıt grading and truck loading iş akışları.

Supports Smalian, Frustum, Mean diameter, and custom multiplier rules Calculates batch rows for multiple kayıt lots in one ekran Normalizes density to kg/m3 and volume to m3 internally Tahmins truck load ratio and approximate truck count from payload

What this tool can do

  • Tahmin kayıt volume from small-end diameter, butt-end diameter, and length with a choice of volume rule.
  • Convert density tables to kg/m3 internally so that local units and reference values stay comparable.
  • Track many kayıt lots at once and keep a kaba inventory record for the yard or landing.
  • Tahmin truck load ratio, remaining payload, and approximate truck count when kapasite is entered.
  • Save the current conditions in the tarayıcı, a paylaşım URL, JSON, or CSV depending on how much data you want to carry.

How to use

  1. Choose the measurement sistem and the default diameter, length, and weight units.
  2. Enter small-end diameter, butt-end diameter, length, and count for each kayıt lot.
  3. Pick a volume rule and a density profile, then check the resulting volume and weight.
  4. Add truck kapasite if you want a payload ratio and an approximate truck count.
  5. Use JSON or CSV export to paylaşım the current state, or save the page locally for later use.

Examples

Metric kayıt lot

Girdi

Small-end 18 cm, butt-end 28 cm, length 4 m, count 20, density 860 kg/m3, rule Smalian

Çıktı

About 0.174 m3 per kayıt, 3.48 m3 per lot, and about 2.99 t total weight

Imperial kayıt lot

Girdi

Small-end 7 in, butt-end 11 in, length 16 ft, count 10, density 54 lb/ft3, rule Smalian

Çıktı

About 7.42 ft3 per kayıt, about 399 lb per kayıt, and about 3,990 lb total weight

Regional override

Girdi

Apply a Smalian × 0.92 regional factor and replace the density table with a local reference set

Çıktı

The difference from the default values becomes visible so that teams can align on one paylaşımd assumption

Glossary

Small-end diameter

The diameter at the thinner end of the kayıt. Local rules may treat bark inclusion differently.

Butt-end diameter

The diameter at the thicker end of the kayıt. Some regional rules call it the butt-end diameter.

Smalian

A volume formula that multiplies the average of the two end areas by the kayıt length.

Frustum

A frustum approximation that uses both end diameters and the kayıt length.

Density

Mass per unit volume. It changes a lot with species, moisture content, and bark assumptions.

Load ratio

The paylaşım of truck payload used by the current load, shown as a percentage of the maximum payload.

Formulas

  • A(d) = π × d2 / 4
  • Smalian: V = L × (As + Ab) / 2
  • Frustum: V = π × L × (ds2 + ds × db + db2) / 12
  • Mean diameter: V = π × L × ((ds + db) / 4)2
  • Weight = Volume × Density
  • Load ratio = Total weight / Truck max payload
  • Approximate truck count = ceil(Load ratio)

SSS

Which volume rule should I use?

Use the regional rule that your yard, mill, or buyer expects. When no local rule is defined, start with Smalian.

Can I enter mixed units?

Yes. The page accepts unit-tagged values such as 18 cm, 7 in, 16 ft, 54 lb/ft3, and 0.86 g/cm3.

Can I paylaşım custom rules or density tables?

Yes. Use JSON export and import for the full libraries. The paylaşım URL is for the current operating state only.

Does the truck payload check enforce legal limits?

No. It only shows an approximate ratio and truck count. Always confirm legal and company limits separately.

Can I use this on mobil?

Yes. The page switches to girdi and çıktı tabs on small ekranlar, and the main calculation stays in the tarayıcı.

Important notlar

  • Density changes with species, moisture content, bark, and local measuring practice.
  • Volume rules also vary by region. Always keep the rule name and basis visible when you paylaşım the result.
  • Truck payload sonuçlar are approximate only. Confirm the actual vehicle spec, road rules, and company policy before dispatch.
  • This page is for estimation and yard management, not for legal overloading checks or structural tasarım.
