HAIR TOOL TEMPERATURE - UNIT AND INSTRUCTION RECORD
Original worksheet. Conversion is arithmetic, not a safe-setting recommendation.

Tool name and exact model:
Market/version, if shown:
Source: current tool, package or matching manufacturer instructions:
Date checked:
Number exactly as shown:
Unit exactly as shown (Celsius, Fahrenheit or not stated):
What the number describes (operating temperature, setting, maximum or other):
Converted value:
Rounding used:
Actual available setting (do not assume the tool offers the converted number):
Instructions to check separately: hair condition, heat setting and use:
What remains unknown or inconsistent:
Manufacturer question to resolve:

Absolute temperatures:
Fahrenheit = Celsius * 9/5 + 32
Celsius = (Fahrenheit - 32) * 5/9
Examples: 185 C = 365 F; 180 C = 356 F; 450 F is about 232.22 C.
Temperature differences use only the ratio: a 10 C change is an 18 F change.

Do not infer a unit from a bare number or a dial numbered 1 to 5.
Do not treat a maximum setting, a conversion chart or a manufacturer's
marketing description as a universally safe temperature for every head of hair.
Temperature conversion does not confirm voltage, plug compatibility,
device calibration or a plate temperature measured in use.
