ConvertAll is a handy tool for the conversion of units, from one format to another, from one base to another, and for the calculation of non-linear expressions.

ConvertAll has a large number of units, from many different categories, and it can be used to convert from one format to another, from one base to another, and also to calculate non-linear expressions.

For example, you can convert from meters to kilometers, from seconds to hours, from money to pounds, from energy to kilowatt hours, from pressure to kilopascal, and many more.

ConvertAll also includes a large number of basic mathematical functions, such as sine, cosine, tangent, and others.

ConvertAll can be used in different ways. You can select a unit from a list and type its full name or its abbreviation.

With ConvertAll, you can combine the units any way you want. If you want to convert from inches per decade, that’s fine. Or from meter-pounds. Or from cubic nautical miles.
