Hex Color to RGB and RGBA Converter
#RRGGBB → rgb(R, G, B) with each channel 0–255.
Paste #1a73e8 or 1a73e8. Shorthand #1ae expands. RGBA is the same three bytes plus an alpha you type. Design tokens that mix hex and rgb() are how themes drift.

How this calculator works
Paste #1a73e8 or 1a73e8. Shorthand #1ae expands. RGBA is the same three bytes plus an alpha you type. Design tokens that mix hex and rgb() are how themes drift. #RRGGBB → rgb(R, G, B) with each channel 0–255. Example: #ffffff → rgb(255, 255, 255). #000 → rgb(0, 0, 0).
#RRGGBB → rgb(R, G, B) with each channel 0–255.
Example: #ffffff → rgb(255, 255, 255). #000 → rgb(0, 0, 0).
When to use this Hex to RGB
Common use cases
- Paste #1a73e8 or 1a73e8. Shorthand #1ae expands. RGBA is the same three bytes plus an alpha you type. Design tokens that mix hex and rgb() are how themes drift.
- Sanity-check with this case: #ffffff → rgb(255, 255, 255). #000 → rgb(0, 0, 0).
- The relationship is: #RRGGBB → rgb(R, G, B) with each channel 0–255.
Localized examples

How to Convert Hex to RGB Step-by-Step
- 1Enter Hex. Use the values you have, not a catalog average, unless that is all you know.
- 2#RRGGBB → rgb(R, G, B) with each channel 0–255.
- 3Worked case: #ffffff → rgb(255, 255, 255). #000 → rgb(0, 0, 0).
- 4Check which dictionary the other person is using — US or UK, decimal or 1,024 — then trust the number.
Governing formula
#RRGGBB → rgb(R, G, B) with each channel 0–255.
#ffffff → rgb(255, 255, 255). #000 → rgb(0, 0, 0).
Example: set Hex = 0, then read the result.

- ASCII / Unicode Code PointsType a character, a decimal code, 0x41, or U+1F600. You get the code point, hex, binary, and UTF-8 bytes. ASCII is 0–127. Everything else is Unicode. This is not an encoding converter for files — it is one scalar value at a time.

Unit Converters
A 5K is 5,000 meters, not 5 kilometers on the nose if your watch is sloppy. Divide meters by 1,000. Track races, building plans, and “how far was that hike” all live in this split.
Feet to Meters
Unit Converters
US height, ceiling height, and lumber still arrive in feet. Meter plans do not. One foot is exactly 0.3048 m — not “about a third.” Use this when a listing says 10 ft ceilings and the architect works in meters.
Inches to Centimeters
Unit Converters
Monitor diagonals, waist measurements, and photo prints still come in inches. Clothing charts in Europe come in cm. Multiply inches by 2.54. That factor is exact, not a kitchen guess.

Very usable on mobile. Would love a save/export option later, but the math feels solid.
