Mechanical engineer overseeing formula verification, reference sourcing, and accuracy methodology across MegaCalc’s calculators and unit conversions. Also runs MegaConvert and MegaText, and develops iOS apps under the Bytecove Software label.
Background
Christopher Floied holds a Bachelor of Science in Mechanical Engineering (BSME) and founded MegaCalc to build the engineering reference site he wished existed during his coursework and early career. The premise is simple: a mechanical engineer needs hundreds of different calculators across statics, dynamics, thermodynamics, fluid mechanics, heat transfer, machine design, controls, and materials — and most existing tools are either ad-laden, paywalled, or scattered across a dozen separate websites with inconsistent units and unclear sources.
MegaCalc is the alternative: a single free site that brings the full undergraduate mechanical engineering curriculum together with the everyday unit conversions, currency tools, and engineering references practicing engineers actually use day to day.
Areas of Engineering Competency
Statics & rigid-body equilibrium
Dynamics & kinematics
Mechanics of materials (stress, strain, deflection)
Thermodynamics (cycles, properties, steam tables)
Fluid mechanics & pipe flow
Heat transfer (conduction, convection, radiation)
Machine design (gears, bearings, springs, shafts)
Controls & systems (PID, transfer functions)
Materials science & manufacturing processes
Unit systems (SI, USCS) and dimensional analysis
Role at MegaCalc
As founder, Christopher architects and maintains the engineering methodology that governs every calculator on MegaCalc. This includes selecting which formulas to publish, choosing which authoritative references to cite (Marks’ Handbook, Shigley’s, Hibbeler, Cengel, Perry’s, ASME BPVC, ISO and ASTM standards), specifying acceptance criteria for accuracy, and reviewing the verification process documented on the Methodology page.
Day-to-day calculator implementation, content writing, and unit conversion tooling are produced by the MegaCalc team using the engineering methodology Christopher has set. Pages on MegaCalc are attributed to “the MegaCalc team” with engineering methodology and reference vetting credited to Christopher — an honest representation of how the platform is built.
Specific engineering calculators in core mechanical engineering domains (statics, dynamics, thermodynamics, fluid mechanics, heat transfer, and machine design) carry Christopher’s direct review of the underlying formula and the reference citations.
Why MegaCalc Exists
Most online unit converters and engineering calculators exhibit two failure modes: shallow content (a converter widget with no explanation, no formula, and no source) or hostile UX (interstitial ads, signup walls, broken mobile layouts). Neither serves an engineering audience that needs both speed and verifiability.
MegaCalc’s editorial standard is that every calculator displays its formula, cites its references, and runs instantly in the browser without an account. Every unit conversion factor is traceable to an authoritative source (NIST, BIPM, ISO 80000, or the relevant ASTM/ASME standard). This is the bar the site is held to.
Other Projects
MegaCalc is one of a small family of tools Christopher has built. Same principles run through all of them: be genuinely free where free makes sense, do one thing well, be honest about trade-offs, don’t store user data longer than necessary.
Free web tools
Three free, no-signup web tools. MegaCalc (this site) is the calculator and unit-converter; MegaConvert is the file-converter companion; MegaText is the developer-tools companion.
MegaConvert is the file-converter companion to MegaCalc. It supports 157+ formats across images, audio, video, documents, fonts, archives, ebooks, 3D models, subtitles, and vector graphics. Free, no account, files deleted within an hour. Hand-written guides on the highest-traffic conversion pages cover what survives the conversion and what doesn't — same editorial standard as MegaCalc.
MegaText is the developer-tools companion to MegaCalc and MegaConvert. JSON formatter, Base64 encoder/decoder, regex tester, diff checker, hash generator, URL encoder, JWT decoder, Markdown previewer, Lorem Ipsum generator — over 160 utilities, all running client-side where possible for privacy. Same principles as MegaCalc: free, no signup, instant results.
Apps Christopher has built and shipped on iOS. The trade-calculator app (FieldCalc Pro) is the one most directly tied to the BSME background; the games and the AI scanner are side projects that wandered into their own audiences.
Code-compliant trade calculators for electricians, HVAC techs, and contractors.
FieldCalc Pro is an iPhone app for trade professionals. 28 calculators with NEC, ASHRAE, and IRC code references built in — voltage drop, conduit fill, panel sizing, duct calculations, equivalent length, load calculations, and more. Designed for use on the job site, not the office. The trade I'm most fluent in (electrical) drove the original feature set; HVAC and contractor calculators followed as I worked with users in those fields.
AI coin scanner — identify, grade, and value any coin or banknote.
Moneta AI is an iPhone app that uses computer vision and a coin-domain language model to identify, grade, and estimate the market value of coins and banknotes. Point your camera at a coin and you get the year, country, mintmark, condition grade, current market range, and (for silver/gold coins) the melt value. Includes an AI Reality Check that flags suspicious or potentially-counterfeit submissions. Free with 5 scans daily.
Cozy tea-themed word puzzle game — 250 levels, ambient sounds, beautiful themes.
WordBrew is a cozy iPhone word puzzle game. Brew words across 250 levels in a tea-shop setting — collect tea cups, customize your shop's theme, unwind with ambient sounds. Built for the kind of low-stress puzzle session you fit between things, not the kind that demands an hour of focus. 10 themed chapters, optional in-app purchases for cosmetic upgrades.
Neon block-breaking arcade game — 400+ levels across 8 worlds.
Blox Breaker is a neon-fueled iPhone arcade game in the classic block-breaker tradition. 400+ levels across 8 themed worlds, premium power-ups, daily challenges, and an endless mode for long sessions. The visual style is the differentiator — synthwave aesthetic, vivid colour, particle effects on every brick break. Premium tier unlocks all power-ups and removes ads.
Custom internal systems, AI integrations, and workflow automation for service-based organizations.
Bytecove Software is the consultancy I co-developed for. We design and deploy purpose-built internal systems — operational dashboards, AI integrations, workflow automation — for service-based organizations that have outgrown spreadsheets but don't need an enterprise SaaS stack. Based in Chattanooga, TN. The same engineering mindset that powers MegaCalc and MegaConvert applies here: read the spec, weigh the trade-offs, build what the work actually needs.
Reach out about engineering methodology questions, formula corrections, calculator suggestions, or potential collaborations via the MegaCalc contact page. Substantive engineering corrections (with a citation) get priority — if a formula or reference is wrong, we want to know and fix it.
