You need to know how much metal you are heating.
Naturally, you need more heat to heat a kilogram of metal than to heat a gram of metal.
The temperature change, in degrees Celsius, is .
The temperature change, in Kelvins, is also , because the Celsius scale is the same as the Kelvin scale, just shifted.
To heat grams of that metal by kelvins,
you would need

.
So, for 10 grams of metal, the heat needed would be 920 Joules.
