Grams, milligrams and micrograms: preserve units in a food-label comparison

A number needs its unit

The U.S. Nutrition Facts panel presents nutrient quantities alongside units and reference information. A copied number such as ten is incomplete without its nutrient, amount basis and unit. Removing units to simplify a table can make unrelated rows appear comparable.

Keep the original beside any conversion

An editorial worksheet should retain the label’s original entry, then place any necessary unit conversion in a separate column. Mark the calculation and its basis. Do not compare a mass figure directly with a percentage or silently convert rounded panel values into more precise claims.

Use the exact pack

Photograph or transcribe the relevant panel carefully, preserving the serving size and market identity. If a unit or digit is unreadable, record the gap rather than guess from a similar product online. This method reduces transcription ambiguity; it neither verifies laboratory composition nor sets personal nutrient requirements.
