Question 1

How does the educational unit converter work?

Accepted Answer

Pick one of 10 categories (length, mass, temperature, time, area, volume, speed, digital storage, energy, pressure), choose the source and target unit, enter a value, and the tool computes the result plus a step-by-step derivation: the formula, the substitution with your value, and the final result with the chosen precision.

Question 2

How are temperature conversions handled?

Accepted Answer

Temperature is non-multiplicative, so the tool uses the standard formulas: °F = °C × 9/5 + 32, K = °C + 273.15, °C = (°F − 32) × 5/9, etc. Each step shows the formula and substitution explicitly. The other 9 categories use a single multiplicative conversion factor relative to a base unit (e.g. meters for length).

Question 3

What units are supported in each category?

Accepted Answer

Length: m, km, cm, mm, mile, yard, foot, inch, nautical mile. Mass: kg, g, mg, ton, lb, oz, stone. Temperature: °C, °F, K. Time: s, min, hr, day, week, month, year. Area: m², km², ft², yd², acre, hectare. Volume: L, mL, gal (US), qt, pt, cup, fl oz. Speed: m/s, km/h, mph, knot. Digital: bit, byte, KB, MB, GB, TB, PB. Energy: J, cal, kWh, BTU. Pressure: Pa, kPa, bar, psi, atm. Total: 59 units across 10 categories.

Question 4

What extra features does this tool have compared to others?

Accepted Answer

(1) 10 conversion categories. (2) 59+ unit types. (3) Built-in conversion factor table. (4) Step-by-step conversion display (formula → substitution → result). (5) Temperature special handler (non-multiplicative formulas). (6) Precision customizer (0-10 decimals). (7) Text report renderer (with steps). (8) CSV renderer (from, to, value, result, formula). (9) Copy + Download .txt + Download CSV. (10) History (localStorage, last 20). (11) Shareable URL (encode inputs in hash). (12) Summary stats (total conversions, by category). (13) Unit search/filter. (14) Common-conversion presets (mile→km, kg→lb, °C→°F, hr→s, L→gal, MB→KB). (15) Bi-directional converter (swap from/to with one click). (16) Formula reference table per category.

Question 5

Is my data sent anywhere?

Accepted Answer

No. All conversions and step generation run locally. History is stored in localStorage on this device only. Nothing is uploaded.
