Calculate diagonal angle-of-view focal-length equivalence from actual focal length and exact source/reference image-area width and height.

Calculate thin-lens near/far focus limits and hyperfocal distance from actual focal length, focus distance, f-number, and an entered CoC criterion.

Calculate EV100 and ISO-normalized setting indexes plus an equal-exposure shutter time from aperture, seconds, ISO, and comparison aperture.

Translate a documented or tested flash guide number to a target ISO, then solve a nominal direct-flash f-number or same-unit distance.

Calculate thin-lens hyperfocal distance and its exact entered-criterion near limit from actual focal length, taking f-number, and explicit circle of confusion.

Calculate the largest whole-pixel golden-ratio candidate rectangle inside a source image, including exact edge exclusions and retained pixels.

Calculate print size at entered image PPI, then audit retained pixels, fill crop, effective PPI, and pixel differences for one exact target.

Reproduce decimal video-file size from documented video/audio bitrates, duration and explicit container overhead, then compare an independent file-size record.

Reproduce and compare active square-pixel sample counts, decimal megapixels and axis ratios for two explicit reviewed raster records.

Reproduce media-set capacity from a reviewed inventory, per-item payload, explicit working overhead and reserve, then compare an independent capacity record.

Reproduce reviewed square-pixel active-image geometry for a documented target canvas using an explicit Fit/Pad or Fill/Crop mode and rounding rule.

Reproduce a strictly sequential render or export queue from two named completed work-and-elapsed-time observations, explicit fixed overhead, and an independent duration record.

Estimate a USD trip budget with separate travel days and hotel nights, rooms, meals, group costs and an allowance; save and compare your planning cases.

Compare two observed offers on one explicit shared denominator, with auditable unit prices, differences, and a true tie state.

Calculate fuel gallons and cost from total trip miles, expected US MPG and an entered price per US gallon. Save planned or observed cases.

Generate a personal packing checklist with explicit laundry intervals. Edit items and quantities, check packed rows, save locally and download Markdown.

Record USD travel receipts and refunds by payer and category, then separately reconcile an approved reimbursement with advances and payments received.
