What this is for: Turns a mg/kg dose into the mg per animal and injection volume at your solution concentration, with cohort totals and a route-volume check.
The formula: dose per animal (mg) = dose (mg/kg) × body weight (kg); volume = dose ÷ concentration (mg/mL)
How to use:
- Enter the dose (mg/kg), stock concentration (mg/mL) and overage for prep (%).
- Enter the body weights (g), one per animal, separated by a newline, space or comma.
- Read each animal's dose per animal (mg) and injection volume (µL) in the table.
- Read the total compound needed (mg, including overage) and total stock solution to prepare (mL).
- Confirm doses, routes and maximum volumes against your approved animal protocol (IACUC) — this calculator only does the arithmetic.
Animal Dose Calculator (mg/kg → per-animal dose & injection volume)
Enter the dose and stock concentration once; each animal's weight gives its mg dose and injection volume.

Notes & limits (from the workbook): Enter the dose and stock concentration once; each animal's weight gives its mg dose and injection volume. The workbook table covers up to 10 animals (blank weight rows are skipped, as here). ALWAYS confirm doses, routes and max volumes against your approved animal protocol (IACUC) — this sheet only does the arithmetic.
