Betong Kalkulator — Beregn mengde betong
Vegg og betong er forhåndsvalgt. Fyll inn lengde, høyde og tykkelse for å se anslått volum i kubikkmeter.
Prisestimat bruker regionale snitt når nok brukere har delt priser (min. 5 per materiale).

Slik regnet vi
Gross wall face area: 20.00 m × 2.20 m = 44.00 m².
Net face area: 44.00 m².
Wall volume (net area × thickness): 44.00 m² × 0.20 m = 8.80 m³.
Concrete mix (1:2:4 rule of thumb): 8.80 m³ → ~62 bags cement (7 bags/m³), sand 3.87 m³, gravel 7.74 m³.
Totalt (mengder)
- Concrete: 8.80
- Cement bags: 62.00
- Sand: 3.87
- Gravel: 7.74
Estimert totalsum: NOK 0.00
* Mengder inkluderer standard svinn der det er angitt: tegl +10 %, flis tak/gulv +10–15 %, membran +15 % overlapp. Andre materialer følger grunnberegning — legg til egen margin ved innkjøp.

What this tool does
Betong Kalkulator — Beregn mengde betong helps you get to a clean result quickly without extra setup. It is designed for practical workflows where you need a reliable output you can copy, download, or reuse immediately. ConvertPal runs core transformations with clear labels and predictable defaults, and pairs the tool with short best-practice guidance so you can avoid common mistakes. If you are comparing options, start with the primary use case below, then follow the recommended next steps to keep the workflow consistent across your site. For advanced needs, combine this page with related tools to validate inputs, generate supporting copy, or standardize naming.
Vegg og betong er forhåndsvalgt. Fyll inn lengde, høyde og tykkelse for å se anslått volum i kubikkmeter.
Common use cases
- Turn sketch dimensions into an order-of-magnitude materials list before you call a ready-mix plant or builder’s merchant.
- Compare two schemes (thick wall vs thin wall, different roof pitches) by duplicating structures side by side.
- Export a PDF quote draft when you are on a paid plan and need a shareable paper trail.

Quick FAQ
Hvor mye betong trenger jeg til en vegg?
Multipliser veggflate (lengde × høyde minus åpninger) med veggtykkelsen for volum i kubikkmeter. Kalkulatoren er forhåndsinnstilt med vegg og betong.
Hvilke enheter brukes?
Du kan skrive lengder i meter, cm, mm, fot eller tommer; verktøyet regner om til meter og viser betongvolum i m³.
Inkluderer dette svinn?
Resultatet er geometrisk volum. Legg gjerne til noen prosent ekstra på byggeplass for spill og ujevn støp.
Key benefits
- Estimate ready-mix, cement, sand, and gravel from wall and slab volumes.
- Quantify bricks, tiles, screed, insulation, and membrane from dimensions you already know.
- Turn supplier unit prices into an on-page quote range you can sanity-check in minutes.
What this tool does
All geometry is converted to metric meters internally, then standard rules of thumb turn volumes and areas into material quantities (for example cement bags per m³ of concrete, tiles per m², and common wastage factors). Related utilities on ConvertPal include Concrete Volume Calculator, Room Area Calculator, and Cubic Meter Converter.
Openings subtract from wall face area before volume is calculated, so window and door deductions behave like a simple quantity survey worksheet.
Nothing is sent to a server for the math: your dimensions, selections, and optional prices can be remembered locally in your browser so refreshes are less painful on long estimates.
How to use it
- Choose metric or imperial display, your currency, and optionally name the project.
- Add structures (walls, slabs, roofs, or custom area/volume) and enter dimensions.
- Select materials, optionally type supplier prices, and read quantities, line costs, and the expandable calculation notes.
- On Creator (paid), export a branded PDF or CSV for sharing with clients or your purchasing team.
