• Likewise, make sure that any published regulations you use are for,
or have been converted to, the scale you are using. In the past, most
regulations have intended Hortvet correlation, whether “Celsius”
was specified or not. Verify by checking the standard solution
freezing points referenced; if 422 and 621 (or not specified at all),
the regulations probably were Hortvet correlated.
