Estimate the static tension of a guitar string from its linear mass density, speaking length, and vibrating frequency. Enter the string's mass per unit length in kilograms per meter, choose the unit displayed by its package or data sheet, and provide the scale length and target note frequency. The estimate uses the ideal flexible-string equation and does not account for a particular instrument's construction or playing conditions.

Convert a pixel measurement to centimeters using the selected pixel density in pixels per inch (PPI).
Convert a pixel measurement to inches using a specified pixel density in pixels per inch (PPI).
Estimate total playlist playback time from the number of tracks and their average length. The estimate assumes every track plays once at its entered average duration and excludes gaps, repeats, and playback-speed changes.

Estimate the solution cost for cleaning a batch of vinyl records using your records, solution used per record, and solution price per liter.
Estimate the duration of an encoded audio file from its size in bytes and bitrate in bits per second. The estimate excludes container overhead.
Estimate a room’s RT60 reverberation time with the Sabine equation from room volume and total equivalent sound absorption area. Use cubic metres and square metres for the inputs to get seconds.
Convert red, green, and blue channel values from 0 to 255 into a six-digit hexadecimal color code.

Calculate the wavelength of a sound wave from its frequency and the speed of sound in the medium.
Calculate the nominal total impedance of identical speakers wired in series or parallel. Enter the impedance of one speaker and the number of speakers to estimate the load in ohms.
Estimate a stereo listening position from speaker spacing using an equilateral-triangle layout. The result is the recommended distance from each speaker to the listening position, assuming both speakers and the listener form an equilateral triangle.

Estimate a speaker's sound pressure level at a chosen listening distance from its sensitivity rating and amplifier power, using an ideal free-field model.
Estimate electrical power in an ideal resistive load from RMS voltage and resistance. This calculation does not determine a loudspeaker’s rated power handling or recommended amplifier settings.
