The difference
35 kcal burned
The two use the same push and glide, so the numbers are close. Rollerblading at about 14 km/h comes out a touch higher than general ice skating.
Go faster on either and it climbs: a fast hour on rollerblades, around 18 km/h, is about 720. These numbers are for about 70 kg.
Skate on ice in winter and on wheels in summer and you have it all year. In Caltype just type "rollerblading 1 hour".
