Equations, converters and calculators

Interactive equations & graphs

• Discover hundreds of practical equations and worked examples, use the built-in Equation Solver to calculate, and export your calculation(s) for reports or sharing knowledge.
• Create a worksheet from scratch by combining text, math, images, and plots. Have easy one-click access to a toolbox containing math functions, engineering units, programming structures, and math symbols used in engineering formulas.

Unit converters

Access to approximately 1,000 built-in units for use with over 80 engineering properties. You can save and access user-created units, mark and sort favorite units, and create your own default settings.

Calculators

Streamline calculations that are time-consuming to perform by hand, but not so complicated as to necessitate using a specialized software program. Embed the relevant formulas directly into Excel workbooks, then enter input data and quickly get the answer you seek within a software program that you already use every day. Direct links to the source content and additional related material are provided in the spreadsheets for all calculations.
