What’s on the Dosage Calculation poster
The rule, 3 worked examples, and the mistake everyone makes.
- Divide what you want by what you have, then multiply by the volume it comes in.
- (Want ÷ Have) × Volume = amount to give
- Want 750, have 500/5 mL = 7.5 mL
- Want 0.25 g, have 125 mg = 2 tablets
- Want 40, have 100/mL = 0.4 mL
- Common mistake: Dividing grams by milligrams. → Converting to one unit, then dividing.
Educational reference. Figures here are hypothetical teaching numbers. Real doses come from the prescription and are independently checked.

- Who is the Dosage Calculation poster for?
- Dosage Calculation belongs to the Nursing section rather than to a school year, because life science is not something one grade owns. Anyone learning pharmacology can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Dosage Calculation poster?
- Convert the units before you divide. Almost every error is a units error. A wall chart earns its place by being glanceable from where the work is happening, so Dosage Calculation belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Dosage Calculation?
- Adverse Drug Reactions, Agonists & Antagonists and The Analgesic Ladder sit alongside Dosage Calculation in the Nursing section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Adverse Drug ReactionsAgonists & AntagonistsThe Analgesic Ladder
- Is the Dosage Calculation poster free to download and print?
- Yes. Dosage Calculation downloads as a free PDF with no account, no email and no watermark, like everything else in the Nursing section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Dosage Calculation poster print at?
- Dosage Calculation is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Dosage Calculation loses nothing.Printing guide
