Who can convert the spring rate lb in kg ?
Example 300 lb = ? kg, or something like that ,


Thanks

Creepy

1 kg is 2.20462 lb (and that was from memory too, how sad).

Rule of thumb (that you can remember) is "two and a quarter pounds of jam weighs about a kilogramme"..... Even more sad!

How about this?
