About N1RO
A platform for practical tasks
N1RO brings together calculators and selection tools for tasks such as estimating material quantities, understanding equipment requirements and comparing technical options. The catalog groups tools by the job they help with. Each card identifies the language and market so you can choose an appropriate starting point.
Editorial responsibility
The N1RO platform operator is responsible for the catalog and its publishing rules. Questions and corrections can be sent to admin@n1ro.com. We do not present invented engineer profiles, laboratory credentials or product-testing experience. A calculation or product listing is not a claim of professional certification.
What makes a separate tool
A tool should solve a distinct problem using relevant inputs and a transparent model. Different spellings, sizes or search phrases are not reasons to publish another copy. Where tasks overlap, our publishing policy favors improving an existing tool.
Language and scope
The main catalog is in English. Linked tools can serve different languages and markets; their units, examples and product availability should be checked before use. Technical estimates must be interpreted within the assumptions and limitations of the individual tool.
