🔨 MAKER MATH
•Metric / Imperial Fraction Converter: Convert mixed fractions (e.g. 5 3/16", 2 4/5") to decimal inches, millimeters, centimeters, and meters. Features intuitive unidirectional flow and persistent last-used unit preferences.
•Board Foot & Lumber Estimator: Calculate board feet (BF), linear footage (LF), and total material cost for woodworking and construction projects.
•Surface Area Calculator: Calculate single and multi-surface areas for square, rectangular, and round surfaces in sq ft, sq in, sq yd, sq m, sq cm, and sq mm.
•3D Volume Calculator: Calculate 3D volume for boxes, cylinders, cones, and spheres with live multi-object totals in cu ft, cu yd, cu m, and Liters.

⚡ TECH & ENGINEERING SUITE
•Interactive Ohm’s Law & Power Solver: Solve Voltage (V), Current (I), Resistance (R), and Power (P) simultaneously. Type any two values to solve the rest with real-time conflict detection and engineering unit prefixes.
•AC Power Calculator: Compute Single-Phase (1Φ) and Three-Phase (3Φ) real power and amperage with adjustable power factors.
•AWG Wire Ampacity & Voltage Drop: Calculate voltage drop, delivery voltage, and percentage drop across standard copper AWG conductor gauges (AWG 14 to 4/0). Includes embedded NEC 75°C ampacity ratings and 3% voltage drop safety warnings.
•Subnet & CIDR Mask Calculator: Calculate CIDR prefixes, subnet masks, wildcard masks, network/broadcast addresses, and usable IP host ranges.
