convert_wind_speed {weathermetrics}

Convert between wind speed metrics

Description

This function allows you to convert among the following wind speed metrics: knots, miles per hour, meters per second, feet per second, and kilometers per hour.

Usage

convert_wind_speed(wind_speed, old_metric, new_metric, round = 1)

Arguments

wind_speed

A numerical vector of wind speeds to be converted.

old_metric

The metric from which you want to convert. Possible options are:

• knots: Knots

• mph: Miles per hour

• mps: Meters per second

• ftps: Feet per second

• kmph: Kilometers per hour

new_metric

The metric to which you want to convert. The same options are possible as for old_metric.

round

An integer indicating the number of decimal places to round the converted value.

Value

A numeric vector with wind speed converted to the metric specified by the argument new_metric.

Examples

data(beijing)
beijing$knots <- convert_wind_speed(beijing$kmph,
   old_metric = "kmph", new_metric = "knots")
beijing

data(foco)
foco$mph <- convert_wind_speed(foco$knots, old_metric = "knots",
   new_metric = "mph", round = 0)
foco$mph <- convert_wind_speed(foco$knots, old_metric = "knots",
   new_metric = "mps", round = NULL)
foco$kmph <- convert_wind_speed(foco$mph, old_metric = "mph",
   new_metric = "kmph")
