Mengenai Watt Calculator

Who We Are — Siapa Kami

Watt Calculator is an independent digital engineering initiative and educational resource developed by an international team of licensed professional engineers (PE), electrical engineering researchers, software architects, and STEM educators. We are united by a common conviction: mathematical rigor in electrical science should be accessible, instant, and completely transparent to everyone.

Our team brings together over 40 years of combined hands-on experience spanning industrial power distribution, commercial electrical contracting under National Electrical Code (NEC) standards, renewable solar-plus-storage engineering, and low-power embedded circuit design. We build tools that bridge the gap between abstract textbook formulas and real-world job-site application.

What We Do — Apa Yang Kami Lakukan

At Watt Calculator, we research, engineer, calibrate, and freely publish high-precision computational tools for electrical power calculations, unit conversions, and circuit analysis. Our platform serves licensed electricians, power systems designers, electrical contractors, university researchers, and vocational students across 19 specialized calculators:

All calculations are performed entirely client-side directly within your device's browser using 64-bit floating-point math. No inputs or electrical parameters are ever transmitted to remote servers, guaranteeing total data confidentiality, zero network latency, and instant results even when disconnected from the internet.

Our Story — Kisah Kami

Watt Calculator was founded out of a shared frustration with the state of online technical tools. In late 2023, while teaching electrical engineering coursework and conducting field audits for industrial facilities, our founders noticed a recurring problem: existing online electrical calculators were either bloated with intrusive pop-up advertisements, hid their mathematical logic behind mysterious "black-box" buttons, suffered from floating-point rounding errors, or required invasive user registrations and constant internet connectivity.

In early 2024, we set out to build a modern alternative rooted in an uncompromising principle we call the Open Formula Mandate: every calculation must display its intermediate algebraic derivation in real time, normalize to base SI units, and execute 100% locally in the browser with zero tracking.

What started as a single, clean Watt-Volt-Amp-Ohm solver quickly resonated with apprentices, journeyman electricians, university professors, and robotics hobbyists worldwide. In 2025, we expanded the platform into a comprehensive suite of 19 specialized calculators—ranging from 3-Phase industrial AC and EV charger ratings to solar photovoltaic sizing and NEC 2026 wire ampacity tables—and completely localized the entire experience into 18 native languages.

Today, Watt Calculator serves hundreds of thousands of engineers, tradespeople, and students each month. We continue to operate as an independent, ad-respectful engineering utility committed to accuracy, privacy, and open STEM education.

Ketelusan Matematik: Mandat Formula Terbuka

Watt Calculator memaparkan terbitan formula matematik secara langsung dalam masa nyata:

• Ketelusan formula: masukkan dua nilai dan formula yang digunakan akan dipaparkan serta-merta.
• Ketekalan unit: semua nilai ditukar secara automatik kepada unit asas SI.
• Pengiraan tepat: kesemua 12 variasi hukum Ohm dan Watt dinilai secara tepat tanpa ralat.

Pematuhan Piawaian Kejuruteraan Elektrik

Algoritma kami mematuhi piawaian kejuruteraan elektrik antarabangsa (IEEE, IEC, Suruhanjaya Tenaga):

Seni Bina Privasi Tempatan-Utama

Kami percaya bahawa data kejuruteraan dan kiraan anda adalah hak peribadi anda. Tidak seperti portal lain yang menghantar data ke pelayan analitik:

• 100% Sisi Klien: Semua operasi aritmetik dan penukaran berlaku secara eksklusif dalam enjin JavaScript penyemak imbas anda.
• Tiada Akaun Diperlukan: Akses serta-merta tanpa pendaftaran, halangan bayaran atau langganan wajib.
• Sifar Penghantaran Data: Kami tidak pernah merekod atau menghantar voltan, arus atau parameter litar anda.

Lembaga Penasihat & Semakan Pakar

Alat pengiraan disemak secara berterusan oleh jurutera bertauliah dan pensyarah universiti.

Ujian berautomasi 64-bit memastikan ketepatan daripada tahap milivolt hingga megavolt.
