The "Converter for Calculated Fields Form" plugin makes available to users the CFFCONVERTER operation.
The CFFCONVERTER operation accepts four parameters: value, current unit of measurement, the new unit of measurement, precision (optional).

The second marketplace member is the "WooCommerce Products And Variations Prices for Calculated Fields Form" plugin.
With the "CFF - WooCommerce" add-on, it is possible to integrate the form into the WooCommerce products to access their prices. However, the "WooCommerce Products And Variations Prices for Calculated Fields Form" plugin extends this possibility to the rest of the plugin's versions.
The "WooCommerce Products And Variations Prices for Calculated Fields Form" plugin generates the woocommerce_cpcff_product_price variable in the products pages, and the get_product_price operation. For form inserted into the products' pages, it is possible to use the product's price by using the woocommerce_cpcff_product_price variable as part of the equation. On other pages, it is possible to access the products' prices by calling the get_product_price operation, passing the products' ids as a parameter.
For example, assuming you have a product whose price corresponds to one square meter of the product, and the form includes two number fields, fieldname1 and fieldname2, for the width and length, respectively. And you want to calculate the cost of covering the area. The equation in the calculated field that calculates the cost would be:
fieldname1*fieldname2*woocommerce_cpcff_product_price
If you configure the WooCommerce product as "variable" and every variation (corresponding to the different colors of the product) has associated a price, the previous equation would be the same. The plugin will update the cost every time the user selects a different variation (color).
If the form is not inserted on a product's page, but you need the product's price given its id, assuming the product's id is 123, you can implement the previous equation as follows:
fieldname1*fieldname2*get_product_price(123)
Both plugins complement the "Calculated Fields Form" plugin.
