Unit converters
The conversions that come up constantly in peptide work — mass scale, syringe volume, molar amount, temperature, and length — each self-contained. Type in any field; the others update.
Mass — mg · mcg · ng ?
Volume — mL · U-100 syringe units ?
Amount — mass ↔ moles ?
Temperature — °C ↔ °F ?
Length — mm ↔ inches ?
How to use these
- Mass1 mg = 1,000 mcg = 1,000,000 ng. Type into any box and the other two follow.
- VolumeOn a U-100 insulin syringe, 1 mL = 100 "units." So 0.1 mL is 10 units. Type mL or units.
- Amount (moles)Converts mass to micromoles (µmol), a count of molecules. This needs the molecular weight (MW) — get it from the COA or the property calculator.
- Temperature°C ↔ °F. Type either box; °F = °C × 9/5 + 32, and °C = (°F − 32) × 5/9.
- Lengthmm ↔ inches. Type either box; 1 inch = 25.4 mm exactly.
Common questions
What's the difference between mg, mcg, and ng?
They're the same scale, 1,000× apart: 1 mg = 1,000 mcg (micrograms) = 1,000,000 ng (nanograms).
What's a U-100 unit?
A mark on an insulin syringe. The barrel is divided into 100 units per millilitre, so reading in units avoids measuring tiny millilitre fractions.
Why do moles need a molecular weight?
A mole counts molecules, and heavier molecules weigh more each — so converting between mass and moles requires the molecule's weight (MW).
How do the temperature and length conversions work?
Temperature uses °F = °C × 9/5 + 32 (and the reverse); length uses 1 inch = 25.4 mm. Type either box and the other converts instantly.
