hi Neel,

both r/3 and bw has table T006, you can see these 2 fields here,

basically they are used for unit conversion,

try in r/3 or bw, SE16 and display table T006,

and press F1 on field ZAEHL and NENNR

you will get info with sample

hope this helps.

Numerator for conversion to SI unit

Use

1. Simplified formula:

Measurement unit = (N/D) x SI unit

2. Complete formula:

A * measurement unit = (A * N/D * 10**E + K) * SI unit

A = number of measurement units

N = numerator

D = denominator

E = exponent (only required in the case of very large or very small

numbers)

K = additive constant (only required for temperature conversions)

Examples

1. Dimension length

Measurement unit mm (millimeter)

SI unit m (meter)

1 mm = (1/1000) * meter

2. Dimension temperature

Measurement unit °F (Fahrenheit)

SI unit K (Kelvin)

32 °F = (32 * 5/9 * 10**0 + 255,37) * K = 273,15 K = 0 °
