Measurement

A semantic Value Type representing physical quantities, combining amount and a unit of measure.

type: data-model · status: draft · abstraction: instance

What it is​

Measurement holds a physical or operational quantity as a number with an explicit unit, such as 10.5 kg, 400 mm or 20 °C. Each Measurement Property identifies the kind of quantity it accepts, so IMOS can convert between suitable units, compare values safely and reject incompatible values.

The platform also understands how measurements combine in calculations. For example, multiplying sheet area by paper basis weight can produce sheet mass, while adding a width to a basis weight is rejected. Measurements that share the same underlying dimensions can still retain different business meanings: width and thickness are both lengths, but IMOS does not treat them as interchangeable automatically.

Percentages, ratios and multipliers do not carry a unit and therefore use Number rather than Measurement. A percentage such as 25% is stored as the Number 0.25.

Why it exists​

Manufacturing is physics. A bill of materials cannot simply state "5 steel". It must explicitly declare dimensions, weights, and volumes. A dedicated Measurement type ensures calculations are safe, conversions are automatic, and tenant data can be reliably exchanged or verified against canonical limits.

Stakeholder summaries​

  • Product — Ensures physical properties on records compute correctly across regions, preventing catastrophic math errors in bill of materials.
  • Investor — Differentiates the system in the manufacturing space by accurately managing physical complexities that generic low-code tools ignore.
  • Marketing — Understands the physics of your business. Handle kilograms, millimetres, and degrees automatically, without manual conversion sheets.
  • Engineering — A unified quantitative value type guaranteeing explicit physical dimensions and managing standardized unit conversions automatically.
