Talverlator

Free browser tools: a scientific calculator with graphing, a multi-counter tallier, and converters for units, number bases, angles, and colors. Data stays on your device.

Scientific calculator

Perform arithmetic and scientific functions (trig, logs, powers, roots, factorial, nPr, nCr). Switch DEG, RAD, or GRAD angle modes and open graph mode to plot expressions. After equals, the full formula remains visible so you can check your work.

Tallier

Track several named counters at once, sort by score or name, optionally show tally marks, and keep a running total. Counts are saved in localStorage on your device.

Converter

Convert length, weight, temperature, volume, area, and time; translate binary, octal, decimal, and hexadecimal; convert degrees, radians, and gradians; and map RGB, HEX, HSL, CMYK, and related color models.
