Welcome to the forum.
Can you give the brand and type of the force transducer and give a link to it ?
The Arduino Uno (from the AVR family of boards) can do calculations with 32 bits integers and even simple calculations with 64 bits integers. But it supports only 32-bit floating point variables.
Other boards with new processors have 64-bit floating point.
For normal bathroom scales and kitchen scales, the HX711 is often used.
