Be patient making a calculation or selecting a new domain.

There are several hundred objects that need to be recalculated internally.

This process may take up to five seconds to complete on the largest tables.


Larger unit is above a smaller unit. Multiply going down the page.

Divide going from a smaller to larger unit moving upwards.


Direct values in red are exact. Blue values are exact but less common.

Blue Beam color for SI units. White Beam color for commonly known names.


Numeral following chart name represents the number of chart units available
