It's mostly English speakers (in colloquial use) and Americans (all the time) that tend to confuse them. Americans are among the few still using the 'same' units for both weight and mass (pounds force vs. pounds mass, which aren't the same at all). If you're just learning this for the first time, you should probably use SI (which uses newtons for force, and kilograms for mass). Otherwise, use slugs and pounds (force), if SI isn't an option.
