Mathematical Italic Partial Differential Symbol
π is the mathematical italic symbol for the partial differential used in calculus notation.
U+1D715
π (U+1D715) is a Unicode math character used to represent the partial differential in formal notation. Itβs commonly seen in equations, typeset documents, and math-oriented design. Copy it using the provided escapes when you need a consistent symbol.
Mathematical Italic Partial Differential Symbol Meaning
The symbol π is the Unicode character βMATHEMATICAL ITALIC PARTIAL DIFFERENTIALβ (U+1D715). It is used in mathematical expressions to denote partial differentiation, typically in contexts where a derivative is taken with respect to one variable while holding others constant. You may encounter it alongside variables and differential terms, such as ββxβ in typeset mathematics, or within frameworks that rely on Unicode math characters. Because it is a dedicated Unicode symbol (not just a styled Latin letter), copying the exact character helps avoid font substitution and ensures consistent rendering across documents and applications.
Common uses
- β’Writing calculus and differential equations with partial derivatives
- β’Labeling variables in math notes, textbooks, and lecture slides
- β’Creating mathematical UI text in web apps and documentation
- β’Designing scientific diagrams and typography elements
- β’Generating Unicode-based equations for editors and publishing workflows
Examples

You may encounter it alongside variables and differential terms, such as ββxβ in typeset mathematics, or within frameworks that rely on Unicode math characters. Because it is a dedicated Unicode symbol (not just a styled Latin letter), copying the exact character helps avoid font substitution and ensures consistent rendering across documents and applications.
What is π (U+1D715) used for?
Itβs the βMATHEMATICAL ITALIC PARTIAL DIFFERENTIALβ symbol, used to express partial differentiation in mathematical notation.
How do I copy π correctly in software or HTML?
Copy the character directly (π) or use the provided HTML entity 𝜕 or the CSS/Unicode escapes like \\1D715.
Will π look the same on every device?
Rendering depends on the font and Unicode support. Using the exact Unicode character and a math-capable font usually gives the most consistent results.
Is π the same as a normal lowercase d or a Greek letter?
No. π is a dedicated Unicode mathematical symbol (partial differential) and should be used as such rather than substituting visually similar letters.
