Which tool do I need?

Calculators: Dekuz's calculators handle everyday number problems: percentages, ratios, fractions, averages and quick number-theory checks like GCD and LCM. Each tool runs in your browser and links to closely related calculators, such as the Percentage Calculator, Fraction Calculator and Ratio Calculator, so you can move between related tasks without leaving the page.

Finance: This hub covers pricing, lending and personal-finance math: loan and interest calculators (EMI, compound interest and simple interest), pricing tools (discount, VAT, markup and profit margin) and budgeting tools (debt-to-income, rent affordability and savings goals). Tools that share a formula, such as the VAT Calculator and Sales Tax Calculator, link to each other so you can compare approaches.

Converters: Dekuz converters translate values between measurement systems, covering length, weight, temperature, area, volume, speed, pressure, energy, power and more, using metric, imperial and other standard units. Related converters link to each other, for example the Speed Converter, Pace Converter and Fuel Economy Converter, since they share the same underlying units.

Text Tools: These browser-based utilities count, clean, sort and transform text, including word and character counters, whitespace and duplicate-line cleanup, case conversion, text reversal and slug generation. Tools built around the same task, like the duplicate-line, empty-line and duplicate-word cleaners, link to each other for quick text-cleanup workflows.

Developer Tools: Common web-development conversions and checks live here: URL and Base64 encoding, HTML entity handling, JSON formatting and validation, and Unix timestamp conversion. These tools link across to related Date & Time and Generator tools, such as the Unix Timestamp Converter linking to the UUID Generator and Date Difference Calculator.

Generators: Quick generators for values you need on demand: random passwords, version 4 UUIDs and Lorem Ipsum placeholder text, each running locally in your browser without an external API call.

Date & Time: Date and time tools cover calendar arithmetic (date differences, adding days, business days), clock-time duration and decimal-hour conversion, and fixed UTC offset conversion. Related tools such as the Date Difference Calculator, Add Days to Date and Business Days Calculator link together for common scheduling tasks.
