Turn top/bottom/side margin percentages into pixel insets for 9:16 vertical video (Shorts, Reels, etc.). Planning helper—not official platform specs.

Convert stitches and rows per 10 cm ↔ per inch for pattern scaling.

Match hook diameter in mm to common US letter / number labels (approximate chart).

Pixels and DPI to print width in inches; handy for photo prints.

Given width and ratio W:H, compute height (or scale both sides by a factor).

Bitrate and duration to estimated file size (Mbps, minutes).

File size and download speed to approximate transfer time.

Vin, R1, R2—no-load output at the divider tap.

Two resistors in parallel—equivalent Ω.

Solve for V, I, or R from the other two values.

Vs, Vf, target mA—ballast R and resistor power.

Byte count using binary 1024 prefixes.

RPM and diameter in inches—rim speed ft/min and m/s.

Sum of three bag dimensions vs airline linear limit.

Tempo to quarter-note length for delay/MIDI math.

mm on plan at 1:N scale to real meters.

Page count double-sided—physical sheets needed.

FPS and duration in seconds—total frames.

Display px and video aspect—inner size and bars.

Word count and words per page—pages to print.

Gauge per 10 cm and width—stitches to cast on.

Address and CIDR—mask, network, broadcast, host range, counts.

Diagonal inches and pixel width/height—pixels per inch.

Two hex colors—contrast ratio and quick AA hint.

Percent-encode or decode text for query strings.

Escape < > & quotes for safe HTML snippets.

Sample rate, bit depth, channels, seconds—uncompressed bytes.

UTF-8 to Base64 and character counts—runs locally.

RF power conversion.
