What does one Btu (th)/second measure?

One Btu (th)/second measures the rate of heat transfer equivalent to one thermochemical British thermal unit delivered per second, representing thermal energy flow.

Why convert Btu (th)/second to milliwatt?

Converting to milliwatt helps translate thermal power into electrical power equivalents, enabling comparison and integration in systems involving both thermal and electrical energy.

Can I directly compare Btu (th)/second values to electrical power?

Not directly, as Btu (th)/second pertains to heat transfer. Electrical power equivalence requires considering conversion efficiencies and system-specific factors.
