NAME

Class::Measure::Scientific::FX_992vb - units of measurement like the CASIO fx-992vb

VERSION

This document describes Class::Measure::Scientific::FX_992vb v0.0.5.

SYNOPSIS

use Class::Measure::Scientific::FX_992vb;
$m = Class::Measure::Scientific::FX_992vb->mass(1, 'u');
print $m->kg();

DESCRIPTION

Create, compare and convert units of measurement as the CASIO fx-992vb. This has little to do with the CASIO fx-992vb itself, the hardware just provides a stable curated scope of range and precision for the 128 constants used in this module so it won't be endlessly updated with more units or more precise constants.

CONFIGURATION AND ENVIRONMENT

None.

DEPENDENCIES

INCOMPATIBILITIES

This module has the same incompatibilities as Class::Measure.

DIAGNOSTICS

This module uses Log::Log4perl for logging.

BUGS AND LIMITATIONS

The values are based on the constants from the CASIO fx-992vb scientific calculator from the 90s, which are based on JIS-Z-8202-1988 (Japan Industrial Standards). These are not the latest standards and should not be used when more accurate values than those displayed in a pocket calculator from that era are expected. For example the 2019 redefinition of the SI base units is not and won't be implemented in this module.

Interval scales

While the CASIO fx-992vb has the constants to convert between Celsius, Fahrenheit and Kelvin - using zero Celsius in Kelvin, zero Fahrenheit in Celsius and degree Fahrenheit in Kelvin/Celsius - Celsius and Fahrenheit are only units on interval scales as opposed to Kelvin which has a defined thermodynamic zero which makes it a unit on a ratio scale. This module does of course convert directly between those scales, but for completeness the constants used in those calculations can also be accessed as class methods.

  • Zero Celsius Class::Measure::Scientific::FX_992vb::zC() as 273.15 Kelvin

  • Zero Fahrenheit Class::Measure::Scientific::FX_992vb::zF() as -160/9 Celsius

  • Fahrenheit Kelvin ratio Class::Measure::Scientific::FX_992vb::FK() as 5/9

Dimensionless quantities

Some constants are dimensionless quantities, which means they are independent of the system of unit used and can't be used to convert between units so they are useless in the functionality of this module. These dimensionless quantity constants are listed here for completeness and are available as class methods.

  • Decibel level difference Class::Measure::Scientific::FX_992vb::dB() as 0.11512925465

  • Neper level difference Class::Measure::Scientific::FX_992vb::Np() as 8.68588963807

  • Fine-structure constant Class::Measure::Scientific::FX_992vb::a() as 7.2973506e-3
