Unit Converter (TI-84 Plus CE)

📘 Free PDF User Guide Available

Want to see exactly how UNITCONJ works before buying? View the free PDF guide with screenshots, menu walkthroughs, solved examples, and quick-reference tables for length, mass, area, volume, speed, temperature, pressure, SI prefixes, rates, angle conversions, distance-rate-time, and decimal-to-fraction conversion.

Conversion categories:

• ✅ Length — SI metric, Imperial, and SI-Imperial crossovers
• ✅ Mass — g, kg, mg, lb, oz
• ✅ Area — m², ft², cm², in², acres, mi²
• ✅ Volume — L, mL, cm³, ft³, m³
• ✅ Speed/Velocity — m/s, ft/s, mph, km/h, and acceleration units
• ✅ Flow Rate — L/hr, mL/min, L/min, mL/s
• ✅ Rate Conversions — per sec/min/hr crossovers with worked SAT examples
• ✅ Temperature — °C, °F, Kelvin
• ✅ Angle — degrees ↔ radians with exact π form
• ✅ Time — seconds, minutes, hours, days
• ✅ Pressure — atm, Pa, kPa, mmHg, torr, psi, bar
• ✅ SI Prefixes — tera to atto, quick convert, custom convert, reference chart
• ✅ Bonus: Distance-rate-time solver and decimal-to-fraction converter

Best for: Chemistry students (dimensional analysis, stoichiometry, gas laws, SI prefix scaling), Physics students (kinematics, unit scaling, pressure), and SAT/ACT-style math and science problems involving rate and unit conversions.

The SI Prefixes section covers the full prefix ladder from tera (10¹²) down to atto (10⁻¹⁸) with three modes:

• Quick Convert — one-tap conversions for the most common prefix steps (milli ↔ base, micro ↔ milli, kilo ↔ base, etc.)
• Custom Convert — choose any "from" prefix and any "to" prefix for a direct conversion
• Reference Chart — on-screen table of all prefix names, symbols, and powers of 10

Convert between 7 pressure units in any combination: atm, Pa, kPa, mmHg, torr, psi, and bar. Select your "from" unit, then your "to" unit — no need to memorize conversion factors.

Preparing for AP Chemistry or AP Physics?

UNITCONJ is already included with the Chemistry and Physics bundles. If you're heading into AP exam season, the full subject bundles give you solvers and references built specifically for AP-level problems.
