Calculate BMI, convert units, track weight changes, and determine ideal body weight. Estimate basic energy needs using Mifflin St. Jeor, Harris-Benedict, and Penn State equations. Adjust for activity, injury, and fever factors.
Provides tools for mechanics and civil engineering. Users can calculate water content, void ratio, degree of saturation, porosity, and more. Includes excavation, compaction, and thrust calculations. Supports Imperial and Metric units.
Explore how develops inflatable spacecraft for atmospheric re-entry. Select materials and shapes to build a . Adjust trajectory to safely guide cargo through extreme heat. Simulate re-entry challenges and test design choices.
Allows users to calculate compressor processes, including overall and stage compression ratios. It includes 19 calculators and data charts for design, operation, fabrication, and maintenance of diaphragm compressors.
The app demonstrates Lorentz contraction, showing how an object's length shrinks at speeds near light. It also illustrates time dilation, where time passes slower for a moving object relative to a stationary observer.
Calculate RF parameters such as impedance, wavelength, return loss, and signal delay. Convert between related values. Compare RF cable and assembly configurations. Access technical specs like insertion loss and power rating.
