Choose the correct dimension
Mass and volume are separate. A mass cannot be converted to volume without a known concentration.
Peptide Unit Converter
Convert mass and liquid-volume units without mixing dimensions. A separate U-100 reference converts volume markings to mL and µL.
LIVE CONVERSION
Mass, volume, and U-100 reference
Mass and liquid volume are calculated separately so the page never implies a concentration that was not entered.

U-100 markings are a volume reference on this page. They do not identify peptide mass without a known concentration.
METHOD & LIMITS
How this calculator works
1 g = 1,000 mg = 1,000,000 mcg. 1 L = 1,000 mL = 1,000,000 µL. On a U-100 scale, 100 markings represent 1 mL.

Peptide Unit Converter FAQ
How many micrograms are in one milligram?
One milligram equals 1,000 micrograms. Multiply mg by 1,000 to obtain mcg.
How many microliters are in one milliliter?
One milliliter equals 1,000 microliters. Multiply mL by 1,000 to obtain µL.
Can milligrams be converted directly to milliliters?
No. Milligrams measure mass and milliliters measure volume. A concentration such as mg/mL is required to connect them.
What does a U-100 marking represent here?
It is a volume reference: 100 equal markings represent 1 mL, so one marking represents 0.01 mL or 10 µL. It does not describe peptide mass.
