unit convertion

Description

• R2Q: Q(m^3/s) = R(mm) * area (km^2) * 1000/(3600*24)

• W2mm: 1 MJ /m2/day =0.408 mm /day, 1 Watt /m2 = 0.0864 MJ /m2/day

Usage

R2Q(R, area = dt * 3.6, dt = 24)

Q2R(Q, area = dt * 3.6, dt = 24)

MJ_2W(x)

MJ_2mm(x)

deg2rad(deg)

rad2deg(rad)

Arguments

R	runoff (mm per dt)
area	basin area (km^2), if area = ,
dt	time duration (hour)
Q	runoff flow (m^3/s)
x	scalar or numeric vector
tmean	daily mean temperature
