Conversion Tools

Free interactive conversion calculators for mg, mcg, mL, U-100 syringe units, concentration and dilution maths.

Simple conversion calculators

Choose what you want to work out. Each calculator uses plain-language questions, instant results and optional example values.

Why separate tools?

Sometimes you only need one conversion rather than the full reconstitution calculator. These focused tools make common unit and concentration calculations faster while keeping the full PeppyCalc calculator available for multi-step calculations.

Important

These tools perform arithmetic only. They do not determine what amount a person should use and do not replace product labelling or professional advice.
