Our goal is accuracy, clarity, and visible arithmetic.
Sources
We prioritize FDA pages and labeling, CDC guidance, DailyMed, ClinicalTrials.gov, and other primary or official sources. Secondary sources may help identify a topic but should not be the sole support for a material medical or regulatory claim.
Calculator standards
Calculators convert all mass internally to milligrams, preserve precision during calculation, and round only displayed results. Formula steps and scale conversions are shown so visitors can independently check the arithmetic.
Medical boundaries
We do not select amounts, products, schedules, treatments, or administration methods. Examples illustrate math only. Pages about research or unapproved substances include prominent regulatory context.
Review and corrections
Pages display a review date when regulatory or safety context is used. We update material content when reliable sources change. Please report possible errors through our Contact page.
