Both calculators run independently — change the inputs on either side to compare results.

Primer Melting Temperature Calculator

Estimate the melting temperature (Tm) of a PCR primer from its GC content and length using the simplified Wallace-rule approximation. Useful for quickly designing and checking primers before running PCR.
