There are many web sites that provide both calculators and
specifications / properties data, but few have combined the two to
make the task of working out equations easier (and more
foolproof). Hopefully these pages will assist in solving some of
the common engineering, electronic and math calculations. There
are several other sites which also provide similar pages, and
these are listed in the G.I.F.T.
Recommended Internet Links page.
The controls within Calculator, Interactive, and Unit
Converter pages can have their results copied / pasted from a
Cookie Clipboard so values can be exchanged easily between
pages.
The data included on this web site is divided into five main
categories as outlined below.
 Calculators: These pages present the formula, solved
for each of its variables, and use Javascript to
calculate the unknown variables, in addition, the measurement unit
for each variable can be adjusted individually so most
calculations can be completed within the one page.
 Interactive: Pages where results are obtained by
selecting values / constants / properties from a data set, which
are then further processed using Javascript to produce the
result.
 Lists: Dynamic (expanding / collapsing) hierarchical
"tree" style single column lists and definitions.
 Tabular: Tables (multiple column lists) where the data
can benefit by being compared with other related values.
 Unit Converters: Conversions between different
measurement units within a defined category.

Calculators.
