About DoMyCalc

What we build

DoMyCalc is a bilingual collection of free practical calculators. We are starting with construction quantities and logistics planning, then expanding into more everyday and professional calculations.

The current collection covers gravel, concrete, geometric volume, shipment CBM, dimensional weight and mixed container loading.

Our standard

Every result should be understandable and reproducible. We show units, intermediate values and the assumptions that materially affect an estimate. Each calculator is reviewed with worked examples, unit-conversion checks and boundary cases before publication.

• Metric and imperial inputs
• Immediate recalculation
• Practical examples and formulas
• Clear warnings where supplier or carrier data must be confirmed

Editorial responsibility

The DoMyCalc product and editorial team writes and reviews the calculators, examples and practical guides. Review dates are shown on calculator and guide pages so readers can identify when the material was last checked.

We prefer primary sources such as standards bodies, carrier documentation and recognized technical organizations. When an operational rule depends on a supplier, carrier or jurisdiction, we state that limitation and link to a source users can verify.

Independent planning tools

DoMyCalc is not a carrier, material supplier or engineering firm. References to third-party standards, carriers or equipment are provided only to help users verify planning inputs.
