About ConvertThings
High-Precision Scientific, Engineering & Culinary Measurement Platform
Our Mission: ConvertThings was engineered to provide instantaneous, mathematically exact unit conversions across 22 physical, computational, and culinary measurement domains without floating-point rounding errors, page reloads, or intrusive clutter.
1. Scientific Calibration & Metrology Standards
Every conversion factor and formula in ConvertThings is verified against primary international metrology standards:
- NIST Special Publication 811: Official conversion factors published by the National Institute of Standards and Technology (SI Guide for the Use of the International System of Units).
- ISO/IEC 80000: International standard for quantities, units, symbols, and thermodynamic definitions across mechanics, electricity, acoustics, and photometry.
- IEEE 754 Floating-Point Compensation: Custom arithmetic normalization eliminates binary floating-point representation artifacts (such as
0.1 + 0.2 = 0.30000000000000004), delivering clean, exact decimal and fractional outputs.
- Culinary Ingredient Density Standards: Kitchen Studio volume-to-weight conversions are calibrated against USDA FoodData Central and King Arthur Baking ingredient density benchmarks (e.g., 1 US cup all-purpose flour = 120 g; 1 US stick of butter = 113.4 g).
2. Specialized Engineering & Trade Capabilities
Beyond simple decimal multiplication, ConvertThings solves real-world trade, workshop, and kitchen problems:
- Carpenter Tape Measure Fractions: Converts decimal inches and metric lengths into standard
1/16″ and 1/32″ ruler markings with explicit tolerance indicators.
- Compound Measurement Resolution: Directly parses and converts mixed-unit expressions such as human height (
5 ft 10 in or 5'10" to cm), parcel weights (2 lbs 4 oz to grams), and elapsed durations (1 hr 30 min to seconds).
- Kitchen Drawer Breakdown: Translates awkward fractional volumes (such as
1/3 cup or 34 mL) into practical combinations of standard measuring cups, tablespoons, and teaspoons.
- 22 Measurement Domains (228 Units): Covers Length, Mass, Temperature, Area, Volume, Speed, Time, Digital Storage (Decimal SI & Binary IEC), Data Transfer Rate, Pressure, Energy, Power, Angle, Fuel Economy, Kitchen & Baking, Frequency, Torque, Force, Volumetric Flow Rate, Typography (W3C 96 DPI), Electric Current, and Illuminance.
3. Open Developer API & Model Context Protocol (MCP)
ConvertThings provides free, public developer infrastructure for engineers, educators, and AI systems:
- Public REST API: CORS-enabled JSON endpoints at
/api/convert and /api/units supporting both structured unit parameters and natural-language queries.
- Model Context Protocol (MCP) Server: Native JSON-RPC 2.0 MCP endpoint at
/api/mcp and standalone CLI/stdio package enabling AI assistants to perform deterministic, hallucination-free scientific unit calculations.
