Package Exports

convert-metric

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (convert-metric) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Convert Metric

Converts a string with imperial units to metric units.

convert( string, sig, strict )

By default, the conversion is casually rounded to four figures with trailing zeros trimmed. The desired number of significant figures can be specified with the optional sig argument. Trailing zeros can be preserved with an optional strict flag.

Usage

var convert = require('convert-metric');

convert('2 ft') // returns '60.96 cm'

Spaces are optional.

convert('3ft') // returns '91.44 cm'

The appropriate metric unit is chosen automatically.

convert('3.281 ft') // returns '1m' (measurements >= 1 m return with m)
convert('3.280 ft') // returns '99.97 cm' (measurements < 1 m return with cm)

Full and plural unit names are recognized.

convert('5 feet', 3) // returns '1.52 m'

Fractional measurements are recognized. (Mixed fractions are not yet supported.)

convert('3/8 in', 3) // returns '9.52 mm'

All recognized measurements in a string are converted.

convert('Remote Switch, 12 ft Lead') // returns 'Remote Switch, 3.66 m Lead'
convert('2 gauge, 72 in', 3) // returns '2 gauge, 183 cm'
convert('3/8 in x 80 ft', 3) // returns '9.52 mm x 24.4 m'
convert('21.83 in L x 6.3 in D x 6.97 in H', 3, true) //returns '55.4 cm L x 16.0 cm D x 17.7 cm H'
